Set of 10 textured circular disks made from ultra-soft flexible silicone – 5 large (13.75" diameter) and 5 small (3.15" diameter). 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 "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.Details:Multicolor13.75" large circle diameter3.15" small circle diameterSet of 10 sensory circles (5 of each size)Use with or without a blindfold2015 Practical Pre-School Gold Award WinnerThe silicone circles are strong, soft to the touch and are non-slipEasily cleaned after use in soapy water or in a dishwasherFor ages 3 and up
