Buy the complete set of floor mirror blocks for first-movers and save! Mirrors are important tools that foster a young child's self-awareness, self-esteem, intellectual curiosity and cognitive development. In an inventive twist, we applied safe, shatterproof acrylic mirrors on a variety of block shapes to encourage a first-mover's mobility, coordination and confidence through exploration and play. Constructed in beautiful, durable birch plywood with no visible screws or joinery and edges that are rounded over and sanded smooth for safety.
