The Concave finds Convex puzzle is a tricky building game where only two of the pieces fit together. Challenging children's fine motor skills, spatial awareness and problem solving abilities. The individual pieces are also great for imaginative building and combining with other Grimm's block sets.
Size: 24 wooden pieces L 6 to 12 cm and H 2.5 cm, in a wooden tray.
