This set of 5 sensory balls made of natural rubber promotes tactile and visual stimulation, and also contributes to the development of children's motor skills. Thanks to their soft material, they are very easy for children to handle. Designed in bright colors and different textures, the smaller balls fit into the larger one, allowing the development of hand-eye coordination. They are made of 100% biodegradable natural rubber and natural pigments. Natural rubber is obtained from the Hevea Brasiliensis plant, specifically from its milky sap known as latex.
