Coloring sets this time.

Toys “R” Us Inc., the leading U.S. toy-store chain, in association with the US Consumer Product Safety Commission on Thursday issued a voluntary worldwide recall of Imaginarium Wooden Coloring Cases made in China because ink on the wooden cases contains lead.

Made by a Chinese vendor and sold from October 2006 through August 2007 in all Toys “R” Us stores and on its Web site, the latest recalled product includes an Imaginarium brand 213-piece set packed in light-tan wooden carrying case.

Each set includes crayons, pastels, colored pencils, fiber pens, a paintbrush, pencil, water , palette, white paint, ruler and pencil sharpener in a light tan wooden carrying case that measures about 14 inches high by 19 inches wide.

Consumer Product Safety Commission (C.P.S.C.), a US regulatory body for children’s products, said some of the black watercolor paint in the kit also contains ‘excessive’ levels of lead, which could be harmful for children’s health if taken in by them.

Retailed for about $20, the coloring sets were made for Funtastic by Danxiang International Trading in Ningbo, China. So far, Toys “R” Us has sold about 8,300 of the art kits nationwide.
