OKK Trading Inc., of Commerce, Calif. voluntarily recalled about 2,000 Interchange Robot Toys because surface paints on the toys contain excessive levels of lead, violating the federal lead paint standard. The recalled robot toys were sold as a four piece set with various colored robots each carrying a gun in one hand and a shield in the other. "Interchange Robot" is printed on the outside packaging of the product. The products were sold by dollar stores nationwide from October 2007 through December 2007 for about $1.
