Our building blocks are large enough for children to use easily. They are made of solid wood, so they won't chip or break during normal play. Our blocks are made of Ponderosa Pine and finished with a non-toxic colored stain that won't come off in your child's hands or mouth. We also offer blocks without stain if you prefer natural wood. We offer a variety of shapes and sizes to help children stack and build by themselves. We believe building blocks help children think independently, build concentration, and increase self-confidence. We are sure you and your kids will be happy with the blocks you receive from us. If you're not, please let us know and we'll find a solution that makes you happy!
