A material that is healthy, natural, soft and supple, taken from the sap of the Hevea tree for a product that babies will love. Easy for little hands to grab, with its integral handle in the shape of Sophie's head. Ergonomically shaped and with different textures on each side for different sensations. Little ridges on one side to soothe the first teeth as they form. On the other side, rounded little bumps to massage painful gums. Ideal to relieve babies at different stages of teething.
