The Hazard Files, Case No. 004. Case No. 003 was a recall: the Lane Company kept making cedar chests for decades after the first patent, the government negotiated a fix, and a chest with its lock removed is legal to sell today. A clacker ball has no fix. On November 19, 1971 the Food and Drug Administration declared an entire design — two hard balls on a string, swung until they collide — a banned hazardous substance. No company, no model year, no recall notice. Fifty-five years later the ban is still on the books, still being enforced, and a genuine one is worth more precisely because it is illegal to sell.
The short version
- The FDA banned clacker balls effective December 19, 1971 (21 CFR Part 191, recodified as 16 CFR 1500.18(a)(7) once the newly formed Consumer Product Safety Commission took over hazardous-substance enforcement). It outlawed the design category outright, not one manufacturer's product.
- The ban has been enforced at least twice on the public record: a federal court in Wisconsin ordered 50,000 sets seized and destroyed from Ace Novelty Co. in 1975–76 (413 F. Supp. 1281), and the CPSC seized about 4,600 "Ker-Bangers" sets from a Phoenix wholesaler in December 1985, after the manufacturer had already gone out of business.
- The regulation carries one exemption: balls fixed to rigid rods around a pivot, held to a single plane, tested to specific drop and cord-strength standards. Every clacker toy sold legally today, including a 2020 US patent, uses that mechanism. A pair on a plain string is the 1971 design regardless of age, and no antique or collector exemption exists in the rule.
- No death is recorded against clacker balls in the federal record. The FDA's own 1971 warning cited four fragment injuries, two small fires from sunlight focused through the balls, and cord-related bruises and chipped teeth as the basis for the ban — and at least one retrospective calls the response a moral panic out of proportion to that record.
- No realized price was found. Every figure below is an asking price: a legal 1990s rigid-mount reissue for under $10, and a seller's "Factory Error Lot RARE" original at $199.99 — for an object that cannot legally change hands as a toy.

What a clacker ball is
Two hard balls hang from a length of cord threaded through a ring or a plastic tab at the center. A player grips the tab, works the hand up and down, and the balls swing into wider arcs until they meet above and below the hand with a sharp crack — the "clack" that named it. Alternate names on period packaging include Klackers, Klick-Klacks, Knockers, Ker-Bangers and Popper Knockers, and none of them describe a different object.
A Western Australian museum holds a set called Klik Klaks, dated circa 1971 and made under license from a US company, Creative Decorative Co. Inc.; its curatorial record separately notes that a similar swinging-ball toy was imported "as early as 1950," two decades before the object most retrospectives treat as a late-1960s American invention. No source in this research identifies who first put two balls on a string.
The mass-market American craze belongs to 1968 through the early 1970s. Scotti, Inc., a division of Spatz Fiberglass Products of Yorklyn, Delaware, began production of its "Clickers" brand in mid-January 1971, one entrant among what contemporary retrospectives describe as hundreds of toymakers producing millions of sets in a few years. A Wilmington, Delaware newspaper, the News Journal, ran a piece on February 20, 1971 — nine months before the federal ban — that already captured both sides of the argument: a father who could not break one with a hammer calling them "unbreakable," and an FDA spokesman conceding, "If we can go to the moon, I suppose we can make a safe clacker."
How the FDA banned it in 1971
The FDA's order ran in the Federal Register on November 19, 1971, under the Federal Hazardous Substances Act. It defined the banned object as "two balls of plastic or other material connected by a length of line or cord or similar connector … intended to be operated in a rhythmic manner by an upward and downward motion," and it found the design presented an "unreasonable risk of personal injury from fracture, fragmentation, or disassembly of the toy and from propulsion of the toy or its part(s)." The order took effect thirty days after publication, December 19, 1971, with a sixty-day grace period for relabeling stock already on shelves.
The stated basis was specific rather than catastrophic: four injuries from flying fragments, two small fires caused when clear acrylic balls focused sunlight like a lens, cords snapping and turning a ball into a projectile, and a pattern of bruised wrists and forearms among first-time users. That is the entire injury record cited for a ban this absolute — a category-wide prohibition, not a recall of one company's run.
The Consumer Product Safety Commission did not exist in November 1971; it was created the following year and took over enforcement of the Federal Hazardous Substances Act from the FDA in 1973. The clacker-ball provision moved with that handoff, from 21 CFR Part 191 to its current address at 16 CFR 1500.18(a)(7), where it remains today. The rule has now outlived the agency that wrote it by more than fifty years.
Two more seizures, a decade apart
On August 5, 1975, Judge Robert W. Warren of the US District Court for the Eastern District of Wisconsin granted summary judgment for the United States against approximately 50,000 boxed sets of clacker balls, an in rem action against the goods themselves, with the claimants named as Ace Novelty Company and M.W. Kasch Company. The court applied 16 CFR 1500.18(a)(7), rejected the claimants' cited exemption under 1500.86(a)(5), and ordered the shipment seized and destroyed. The published opinion is 413 F. Supp. 1281 (E.D. Wis. 1976).
A decade later the same rule was still being enforced against a different company. In December 1985 the CPSC, working with a US Marshal, seized roughly 4,600 units of "Ker-Bangers" clacker balls from Empire Novelty & Concession Supply in Phoenix, Arizona. The manufacturer, Chuck Howard Toy Co. of Inglewood, California, had labeled the sets "SHATTERPROOF"; CPSC testing found the balls "either shattered or cracked" and that handles broke in use. The company had already gone out of business by the time of the seizure, so the Commission's own consumer notice offered no replacement and no recall program — it told owners to throw the sets away.
The test that is also the law
On most objects in this series, authentication and legality are separate questions. On a clacker ball they are the same question, answered by looking at one joint.
16 CFR 1500.86(a)(5) exempts a clacker-ball toy from the ban only when "the connecting members consist of plastic rods integrally molded to the balls and are mounted on a pivot so that movement of the balls is essentially limited to a single plane," and only when the assembly passes the Commission's drop and cord-strength testing. Every clacker-type toy sold as new merchandise today is built to that exemption, including a 2020 US patent (10,617,966 B1, inventor Daniel Pena) that pins two rigid rods to internal gears so the balls stay confined to one plane and adds shatter-resistant material and LED lighting powered by magnetic induction as the balls swing — an engineering answer to a fifty-year-old rule, not a period object.
- Balls hanging from a string, cord or nylon line, free to swing in any direction: the 1971 design. Illegal to sell as a toy at any age, in any condition, however it is packaged.
- Balls fixed to rigid rods that pivot around a center housing, moving in one plane only: a post-ban, tested design. Legal to sell.
- A "for display only" or "adult collectible" label on the listing: irrelevant to the regulation, which classifies the object by its mechanism, not the seller's stated intent.
- "Vintage-style" packaging on a new item: irrelevant on its own. Check the joint, not the box art.
Prowl searches more than twenty vintage marketplaces at once for the legal side of this hobby: reissue clackers, sealed promotional sets still in the box, period advertising, and the cardboard backing cards collectors save separately from the balls.
The look-alikes
An original pre-ban set is usually cast acrylic, roughly two inches across, on a cord running through a metal ring or a molded plastic tab; sealed period stock often survives shrink-wrapped to a printed cardboard backing card. Accounts of the earliest sets disagree on material, which is its own entry in the disagreements section below. Some carried a branded tie-in rather than a generic toy-aisle label: an unopened "Quick Klack Klackers" set was made specifically for the Shakey's Pizza chain by a manufacturer based in Aurora, Colorado, the same promotional logic as the cereal-box premiums this shop has covered before.
A 1990s reissue, sold under names like Trendmasters' "Rap n' Clack," moved to lighter plastic and, going by the exemption's requirements, a rigid mount rather than free string. It looks similar enough at a glance to confuse a casual seller, and it is the object almost anyone encountering "clacker balls" in an American toy aisle after 1985 actually held. The 2020 patented LED version is unmistakable once lit, but at rest its rigid center housing is the same tell as the 1990s reissue: a fixed joint where the original has none.
| What it is | Legal status | How to place it |
|---|---|---|
| Original 1960s–70s set, acrylic balls on a cord, ring or tab center | Banned hazardous substance, 16 CFR 1500.18(a)(7); illegal to sell as a toy | No rigid joint anywhere in the assembly; the whole toy is one flexible connector between two balls |
| Promotional premium, e.g. Shakey's Pizza "Quick Klack Klackers" | Same rule as any other original; a brand tie-in does not change the mechanism | Look for the sponsor's name on the card or the balls themselves; still string-mounted |
| 1990s reissue (Trendmasters "Rap n' Clack" and similar) | Legal; built to the rigid-mount exemption | Lighter plastic, and a fixed center housing rather than a free ring |
| Modern LED / patented version (e.g. US 10,617,966 B1) | Legal; rigid rods on internal gears, single plane of motion | Lights on impact; center housing is visibly a mechanism, not a knot |
Is it legal to sell one
No. 16 CFR 1500.18(a) is titled "Banned toys and other banned articles intended for use by children," and subsection (a)(7) names clacker balls specifically as a "banned hazardous substance" — a stronger and more permanent designation than the recall authority behind Case No. 003. A banned hazardous substance cannot be legally manufactured or sold in the United States in its banned form, full stop, and the regulation contains no exception for age, condition, or a listing that frames the object as a collectible rather than a toy for a child. CPSC's own current Resellers Guide (Publication 254, February 2025) does not name clacker balls, but its general instruction is broader than any single recall list: federal law prohibits selling a product that is itself a banned hazardous substance, which is a standing rule rather than a case-by-case recall notice.
Before you list one
An original string-mounted set found at an estate sale is not this shop's to resell, and the regulation gives no path to make it legal short of replacing the entire connecting mechanism — at which point it is a different, modern object built to a different patent. The CPSC's own instruction to owners of a 1985-seized set was to throw it away, not to hold it for the right buyer. Keep one as a personal, non-selling curiosity if it means something to you; do not list it, gift it into someone else's toy box, or advertise it as an antique exemption that does not exist.
What they sell for
No realized-price record was found for clacker balls in any subscription or open auction database checked for this guide. Every figure below is an asking price, and on this object the asking side of the market includes buyers accepting the legal exposure of a banned-hazardous-substance transaction on their own account, which is not the case for anything else in this series so far.
| Item | Note | Price |
|---|---|---|
| Trendmasters "Rap n' Clack," 1990s legal reissue, pair | Rigid-mount design; freely sold new-old-stock | $7.69–$9.99 asking |
| Original 1960s–70s set, seller-labeled "Factory Error Lot RARE" | String-mounted; price reflects scarcity of a banned object, not a legal market in it | $199.99 asking |
| Specialist vintage-toy dealer inventory | Out of stock at the time of research; the dealer is soliciting sellers rather than quoting a price | No price listed |
| "Quick Klack Klackers," Shakey's Pizza premium, factory-sealed | Listed on a subscription pricing site; figure withheld without a paid account | Not disclosed |

Where the records disagree
What the balls were made of has two different answers. A specialist vintage-toy dealer states plainly that original clackers were "never glass despite their appearance," describing the material as a dense plastic. A separate retrospective account describes the earliest 1968 models as tempered glass, which shattered and drove the industry to acrylic before the 1971 ban. Both claims come from secondary retrospectives rather than a period manufacturing specification, and this guide could not adjudicate between them; it names the conflict instead of picking a side.
The ban has no single date in popular memory. One retrospective states clackers "were officially banned from store shelves in 1985" — the year of the Phoenix seizure. The formal FDA order took effect December 19, 1971, fourteen years earlier. Both events are real and both are documented above; the 1985 seizure is evidence the design was still being sold under the same 1971 rule, not a second, later ban.
How dangerous the toy actually was is itself disputed, in a way none of the other three Hazard Files cases have been. The federal record's entire injury basis is the four fragment injuries, two fires and bruising cited in 1971. At least one retrospective account frames the ban as "the most ridiculous moral panic," noting the craze burned out within about eighteen months on its own fad cycle and quoting a period doctor's assessment that "clackers were crackers." No source in this research disputes that the balls could shatter; several dispute whether a federal ban was a proportionate response to what was actually reported.
No source names who invented the toy or when the first pair reached the United States. Museums Victoria's own record hedges between a licensed circa-1971 Australian product and toys imported "as early as 1950."
The case file: cases 001 to 004
Case No. 001, lawn darts, was also banned outright rather than recalled, which makes it the closer relative of the two. The difference is the injury record behind each ban: lawn darts carry three documented deaths; clacker balls carry none. A federal agency can and did draw the same administrative line, a permanent ban with no antique exemption, over two very differently supported cases — which is itself a fact worth carrying into how this series reads every future entry's government action column, not just its deaths column.
Case No. 005 has not been chosen. Read the rest of the series from the Field Guides index, and see Case No. 002, the Gilbert Atomic Energy Lab, and Case No. 003, the Lane cedar chest, for the two cases this one was built against.
