Klean Kanteen Insulated TKPro 16 oz (Brushed Stainless)
BronzeBronze: plastic-free in every known part, with at most one named seal or sealed module; minor parts may still be unverified and are listed as unknown
A steel bottle with a steel cap and a steel cup, and nothing else we can find that you'd call plastic. The catch is the seal: two silicone rings inside the twist-and-pour cap. That's what makes it Bronze. It's the brushed finish only; every painted TKPro wears a plastic powder coat. We don't yet know what else is inside the cap, or what the logo, the base cap and the vacuum plug are made of, and we've asked Klean Kanteen. The maker's own page is gone and US sellers are sold out, so for now the live seller is Babipur in the UK.
- Caveat
- Two silicone gaskets inside the cap, not one. Brushed Stainless only; the painted colors carry a plastic powder coat. Unknown, and asked about: what else is inside the cap, the logo, the base cap, and the vacuum plug and welds. The maker's own page returns an error and US sellers are sold out; Babipur (UK) sells it at GBP 38.95. Packaging not checked.
- Unverified
- Still unverified, and being researched with the maker: cap internals beyond the gaskets (pour-through mechanism, any liner or insert); vacuum seal plug and joints; logo; base cap.
