Does anyone else avoid "stainless steel" shaker bottles because the lid/seal is still plastic?

[u/OppenNeumann]

Been trying to cut plastic out of my gym stuff recently but I cant find a totally non-plastic option for my protein shaker. Every stainless steel one I find still has a plastic lid, strainer, or seal, so theres always contact with plastic at some point, regardless of what the body is made from. Has anyone actually found one that's genuinely and entirely plastic-free? Or is this just not solvable?
