Grimm's Concave Finds Convex consists of 24 interlocking wooden building blocks arranged as a beautiful jigsaw puzzle. The blocks are tactile and can be used as dominoes, for stacking, and for building towers. Children will also benefit from using the blocks in colour sorting activities and in arranging them as mandalas. Each piece has its own matching pair, and together they form a square.

Being hand-finished, each of Grimm's beautiful offerings is unique, with slightly different shaping, wood markings, grain, and knots showing through the dyes, and paint finishes. Please note they are not varnished nor lacquered, leaving the timber with a beautiful textural feel. Because of this, some minor paint transfer may occur during play. This is considered normal.
