Invite children to build thoughtfully and organically with these Wood Stackers Standing Stones. Inspired by prehistoric building blocks, these geometric, wooden stones foster a child's curiosity for creating ancient structures using organic, natural materials. Each wooden block is sanded to a super smooth finish to highlight the beautiful, natural grain and tones of the wood. Different sizes help children understand weight, gravity and relationships. Inspiration cards encourage children to creatively stack and build using the natural blocks to create familiar objects. For indoor/outdoor use. Store indoors in a cool, dry place out of direct sunlight.
