Pura uses stainless steel, which is more hygienic than plastic. By changing the top, you can change a baby bottle into a sports bottle, sippy cup or snack pot. These re-purposed bottles will last years instead of months by simply replacing the silicone top as your child matures.
The Pura Kiki range of stainless steel bottles are 100% plastic-free and independently certified as NonToxic by MADESAFE. They look great too.
