Whether as a shape fitting-game or a clattering motor skills cylinder, this Rolling Sorting Cube toy is really something special! The differently shaped and colorful wooden pieces are designed to be inserted into the corresponding shapes to teach motor skills, and if the toy is laid on its side, it makes a clattering noise when rolled around. The rubber band around the opening prevents the blocks from falling out. Lots of fun, clattering, educational playtime fun for your little!
