This set of 24 animal-themed, chunky, wooden blocks are designed for children aged 12+ months. Made with New Zealand Pine, the pieces are 0.75” (2cm) thick so they stand on their own. There are 12 parent (includes fathers and mothers)/offspring pairs of animals so children can practice their problem solving and role-playing skills. The blocks are screen printed on both sides and lacquered for ease of use and durability. Sizes range from 4”H to 1.9”H.
