Pura Kiki XL Sipper Spouts are made of 100% medical grade silicone, and do not contain plastic, latex, nitrosamines or BPA. They are durable and great for toddlers. The firmer silicone allows for free flow of liquids and natural formation of teeth and gums. They are tinted blue so toddlers will not confuse the new "big boy/girl" spout with a baby nipple.
