Hape toys are designed first and foremost for children. Each product is developed to enhance a child’s developmental skills. Hape believes that the future begins and belongs to our children. It is our duty to leave them with infinite possibilities, not unsolvable problems. Our toys are created to inspire play, learning, and exploration of the world we live in; through responsible business practices we aspire to leave the world in a better condition than when we received it.

We don't accept return, but if the product you receive is broken or wrong, we will provide full or partial refund.
