All-Weather Hollow Blocks 22 Pieces

2 years & up. Children build towers, ramps, bridges, and imaginative structures-engaging in gross motor movement, spatial reasoning, and collaborative problem-solving as they work side-by-side. Block play also encourages early math concepts such as symmetry, size comparison, balance, and geometry, as well as language development through storytelling and peer interaction. UV-resistant material and weather-resistant hardware make this set resilient and ultra-durable in outdoor environments. Scaled to standard Unit Block size to enhance traditional block play. Compatible with traditional unit block sets, this 22-piece kit invites group creativity and supports development across cognitive, physical, and social-emotional domains. Each piece features .6 inch thick hollow walls. 22-piece set includes cubes, rectangular prisms, right triangles and planks.
