Quick Specs
$17 for a cup that grows with your child from infant to toddler (swap the silicone top). Vs. multiple plastic sippy cups that degrade, leach, and get replaced.
Why it's safe for your family
- 100% stainless steel body — no plastic interior surfaces. Your child's drink never touches plastic at any point.
- Medical-grade silicone spout/nipple — the only non-metal component is medical-grade silicone, which does not leach chemicals or shed microplastics.
- No plastic interior surfaces — unlike most sippy cups that have plastic linings, Pura Kiki is stainless steel throughout.
- Grows with your child — interchangeable tops mean one bottle works from infant nipple to sippy spout to sport cap. Buy once.
What to avoid instead
Plastic sippy cups — even those marketed as "BPA-free" — can still leach harmful chemicals into your child's drinks. Heat from warm milk or dishwasher cycles accelerates the breakdown.
Even BPA-free plastic can leach BPS and other endocrine disruptors, especially with warm liquids. These chemicals mimic hormones in your child's developing body. Stainless steel eliminates this risk entirely.
