This all-natural rubber llama teether is pleasant to bite and easy to grip. Textured surface stimulates sore teething gums, while the plump air-filled design provides added satisfaction when chewed. The teether is completely sealed, so there's no opportunity for liquids to be trapped inside. Lili Llama is 100 % natural rubber, eco-friendly, and biodegradable. BPA, PVC, phthalate, and petroleum-free. Hand wash with mild soap and rinse thoroughly. Do not keep natural rubber in direct sunlight or expose to heat, which will accelerate the degradation.
