Buckyballs and Buckycubes will no longer be manufactured due to an ongoing battle between the company that makes them and the Consumer Product Safety Commission (CPSC).

“Due to their baseless and relentless legal badgering, we’ve sadly decided to stop production of Buckyballs and Buckycubes,” according to Craig Zucker, co-founder and CEO of Maxfield and Oberton.

Zucker and his friend originally invested $2000 to invent the popular Buckyballs in a New York City apartment.

In 2009, the product instantly became a top-seller in stores around the world. Since then, the company has sold half a billion products.

These products are marketed for adults, and contain warnings that children should not play with them, according to Zucker.

For years, Maxfield and Oberton worked with the CPSC on safety warnings. Then, without notice, on July 10, 2012, the CPSC Office of Compliance issued a preliminary determination stating that the products are defective since safety warnings do not work.

“We have been betrayed by a government organization that switched overnight from being an ally, helpful in ensuring our products would be marketed correctly, to being an enemy trying to shut us down,” said Zucker.
