This set comprises of 10 textured circular disks made from ultra-soft flexible silicone - 5 large and 5 small. 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 difference: by placing the small circles into the white cotton feely bag provided, they can see if they can 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. Linking the small and the large sensory circles via touch is great fun too with or without a blindfold. Silicone has some great properties which makes it the ideal material for sensory circles - it is strong, safe to handle and ultra-soft to the touch.
