A set of 7 reflective discs for multi-sensory and stacking activities. The stunning, iridescent surface provides a slightly distorted reflection which fascinates children and encourages descriptive language. The reflective surfaces change color in the light as children manipulate the discs. They are smooth and lightweight so children can construct wobbly towers during imaginative play. The discs are chemical-free, non-porous and easy to clean, which makes them ideal for all play environments. Sensory Color Burst Buttons are made of durable, tarnish-resistant stainless steel. Sizes: 1.9"W-5.5"W. Suitable for all ages. Recommended age 0+ years
