Stuka Puka products encourage kids to discover nature, biology or mathematical logic. They are inspired by the Montessori method, Waldorf school and work of Gever Tulley and Richard Louv. The Puzzles are designed and made by themselves with consultation from teachers, psychologists, therapists and doctors to ensure they are accurately designed at their workshop in Poland. They think that learning through play is the best way to hit the minds of their customers. The layered puzzles come in a handy tray with lid to encourage children to tidy away after play.
