Sandwich Blocks is a toy made from three layered pieces of wood. Through the friction between the pieces, blocks can be easily moved, combined, redesigned, arranged, taken apart and put back, and used to create any shape or object. Compared to traditional wooden blocks, this set of blocks is not limited by angles and can be assembled in any position. It can be assembled into jewelry, sculpture, architecture, and characters, not only on the tabletop but also in people’s hands. It is made of dyed plywood for safer play.
