The safest infant feeding bottle on the planet! Pura's award winning 11oz Kiki infant bottles are 100% plastic-free, environmentally progressive, and adapt to the needs of your growing child. Both the bottle and collar are crafted from safe, high grade #304 stainless steel and the teat and travel cover are made from medical grade silicone. The perfect size for little hands, each bottle comes with a soft silicone sleeve which makes holding the bottle easier, a 3+ month teat and a travel cover. The wide mouth allows for easy cleaning, pouring, and filling. This bottle easily converts into a sippy bottle by simply swapping the nipple for another Pura silicone lid.
