The Natural Rubber Soothers Fish Teether is moulded from a single piece of 100% pure natural rubber, tapped from the sap of the Hevea brasiliensis tree. Because it's made in one piece there are no joins or cracks where bacteria can hide, so it stays hygienic through daily use. The fish shape is easy for little hands to hold and soft enough to soothe sore gums through teething. Free from BPA, parabens, PVC, phthalates and chemical softeners, and biodegradable at the end of its life. Twin pack, easy to sterilise.
