Materials and contact
A concise, evidence-scoped look at where plastic and silicone sit in this product’s food, drink, mouth, steam, and condensate paths.
- Plastic contact
- Plastic contact is not fully verified
- Silicone contact
- Some silicone contacts food, drink, or the mouth
Materials and contact path: Klean Kanteen identifies the two straw tubes as certified 90% post-consumer recycled 18/8 stainless steel and their removable black flex tips as food-grade silicone. The tubes and tips contact drinks, and the silicone tips contact the mouth. The included cleaning brush contacts the tube interiors during cleaning, but its complete material composition is not disclosed.
“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.
