Pura Kiki Sippy Cup

Pura created the first 100% plastic-free baby bottle on the market, and they remain the only MadeSafe Certified bottle available. Every component that touches liquid is made from either stainless steel or medical-grade silicone.

What makes Pura clever is the interchangeable lid system. Buy one bottle and simply swap the lid as your child grows: from nipple (newborn) to sippy spout (6+ months) to straw (toddler) to sport cap (big kid). One bottle lasts for years.

The stainless steel body is unbreakable and won't leach any chemicals. They also offer insulated versions that keep drinks at temperature for up to 24 hours, perfect for outings.
