Plan Preschool toys combine learning with fun. Our carefully crafted push-pull toys, manipulative toys, musical instruments, games, puzzles, and blocks are all specially designed to enrich every aspect of your child's early development. These toys inspire children's imagination as well as promoting their physical and intellectual development. PlanToys are made from non-toxic, natural materials such as organic rubberwood. Our toys enable children to play, learn and become closer to nature while being pulled; the wooden pieces make rhythmic click-clack sounds.
