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.",
