This 12-piece building block set stimulates developmental play by encouraging open-ended activities that spark imagination and creativity, improve motor skills, and foster spatial awareness and hand-eye coordination, while its bright colors aid in color identification. Each foam cube is made with a skin-friendly PU leather cover and high-density EPE foam filling, ensuring long-lasting use and shape retention, and the set is ASTM and CPSIA compliant, making it a safe and perfect gift for growing children. The waterproof PU leather cover allows for easy wipe-down cleaning, and tight stitching on the edges enhances tear resistance for long-term durability with minimal maintenance. The soft play equipment is versatile, suitable for stacking, climbing, crawling, and imaginative play at home, daycare, kindergartens, preschools, classrooms, or playrooms, and its compact, stackable design allows convenient storage. The package includes 12 colorful foam cubes in purple, dark blue, lake blue, black, pink, and rose, each measuring 5.5" x 5.5" x 5.5" and weighing 0.2 lbs, with a total net weight of 3 lbs, packaged in a single box, though quantity may vary by batch.
