Versatile and engaging, Hix is fun for all ages and makes an ideal toy for intergenerational play. Babies happily explore its surface with all their senses. The fidgety focus while converting cones into other shapes. The curious and creative nest, stack, and combine multiple shapes into ever changing configurations. When knocked over, Hix blocks tumble down without a sound, providing another lesson in how silicone rubber differs from other materials. Food grade silicone rubber is safe, durable, and easy to clean.
