A wooden puzzle where the pieces lock into one another when placed correctly against one another. An excellent fine motor and visual discrimination toy that provides a fantastic challenge to the child in putting together the pieces. The sixteen pieces are all uniquely cut so that each of them form a complementary pair with another. As the set comprises shapes, it inherently enhances the awareness of geometry and improves dexterity in the child.
