A concise, evidence-scoped look at where plastic and silicone sit in this product’s food, drink, mouth, steam, and condensate paths.
- Plastic contact
- No plastic contact identified in the reviewed scope
- Silicone contact
- Some silicone contacts food, drink, or the mouth
Materials and contact path: Drink and mouth contact: 18/8 stainless steel bottle interior, drinking rim, and cap underside, plus a food-grade silicone cap seal. No conventional plastic is identified in the disclosed drink-contact path; the bamboo cap top is external.
“Not fully verified” means a relevant component, treatment, or variant still needs exact-product evidence. It is not a positive plastic-free or silicone-free claim.
