soulbottles
Plastic-free is the whole premise, not an afterthought. The glass bottles seal with a ceramic stopper and a natural-rubber (not silicone) O-ring held by a stainless-steel swing-top, so nothing plastic or silicone touches the water - which makes them one of the few bottles that reach genuinely plastic-free rather than silicone-only. The closure parts are sold individually as replacements, so the bottle is meant to last rather than be replaced.
How clear are their specs?
Materials are named plainly - glass, ceramic, stainless steel, natural rubber - and each closure part is sold on its own, so what you are drinking from is easy to verify.
Lead testing disclosure
soulbottles' own marketing (FAQ, distributor materials) only asserts the bottles are "100% plastic-free" and "free of harmful substances," with no named lab, no lead/cadmium ppm figures, and no dedicated safety or testing page found. No independent test results (e.g. Lead Safe Mama) specific to soulbottles were found either.
