12 months & up. Little fingers and ears will be engrossed by the Wooden Sensory Blocks Set! Children will enjoy discovering the different textures, sounds, and colors. The eight wooden blocks each have a different sensory experience including a jingly bell, a mirror, a viewfinder, an optical prism, scratchy felt, a cylinder squeaker, and rattle balls. Tots' senses are stimulated through touch, sight, and sound - the sensory blocks are made from smooth wood and child-safe lacquers, making them ok for taste and smell purposes! Ideal for developing the senses as well as dexterity and hand-eye coordination. Made from FSC® Certified wood. Each block measures 1.75" square.
