Kore Design™ Sensory Matching Game Tactile Discs come in two-disc sizes with different patterns and textures. The vibrant colors and raised designs make them well- suited for children to engage in exploration and embrace external stimuli. Our sensory discs provide a fun barefooted and blindfolded game where kids can use their hands and feet to match the little discs with the larger discs. Learn to match and pair the two with the same textured surfaces. Offers a multi-sensory experience, the game teaches children they are capable of more than they think when their eyes are covered. The pieces are designed with strong durable PP-TPE plastic. The bottoms are non-slip to ensure safety. Large Circle Dimensions are 10.23" and the Small Circles are approximately 4".
