Textures, colors, shapes, and words! On one side, each silicone button is embossed with a different shape and labeled with its matching word in English and in Braille. Flip the whole thing over and this time, the buttons are smooth and the words match the colors! It's a tactile delight to touch, push, and pop. Its compact size is perfect for on-the-go. BPA-Free, made with food-grade silicone buttons, and designed just right for little hands, the Dimpl Duo is an ideal way to get the most out of sensory play.
