Activate your senses with these 10 circular textured disks made from ultra-soft flexible silicone. On the surface of each circle is a pattern which is distinctive and different from the rest of the set. Children can feel these textures and discover their differences by placing the small circles into the “mystery bag” provided to describe or predict the pattern they are feeling; or by using their feet they can walk over the large sensory circles to see if they can tell them apart. They are easily cleaned after use in soapy water or in a dishwasher. Set comes with 5 large circles (9-3/4 inches in diameter) and 5 small circles (3-1/8 inches in diameter). BPA and latex free. Appropriate for ages 3 years and up.
