Soopsori is a new line of toys handmade entirely from natural wood finished only with linseed oil, so they are child safe and environmentally friendly. Soopsori uses up to twenty different types of wood, designed to evoke a sense of warmth with their texture and scent. Naturally, all Soopsori toys are tested and pass new CPSA requirements. We can't resist the adorable grins on these little guys. Each of the four blocks in the Rattle Block Set (1 3/4” to 3 1/2” H x 1 3/4” SQ) has a funny face on one side and a distinctive sound when shaken. Too cute!
