Does Simple Modern have lead?

Last reviewed July 2026.

It doesn't say. Read that claim carefully: it covers accessible components. The vacuum-seal point under the base cap of an insulated tumbler is, by design, not an accessible component — and Simple Modern publishes no statement we could locate about what seals it. The claim may be entirely true and the seal may or may not be lead-free; the wording is compatible with either. This is the accessible-components hedge, and it is the single most useful label-reading lesson in this category. Independent XRF spot-checks of individual Simple Modern products have reported accessible components lead-free, consistent with the claim's scope.

How to read this

Nearly every insulated bottle on the market seals its vacuum with a small pellet at the base, and the industry-standard pellet contains lead — sealed under a metal cap, away from the drink and your hands. The questions that separate brands are which sealing method they chose and whether they say so plainly: a documented lead-free seal, an acknowledged-and-encapsulated pellet, or silence. "Accessible components are lead-free" is a carefully scoped claim — see how the sealing methods differ and what a damaged base cap changes.

Which brands document a lead-free seal

Simple Modern not saying is not the same as Simple Modern using lead — we have no evidence either way, which is the whole problem. These brands removed the ambiguity by publishing what their seal is made of.

Documented means the brand states its sealing method publicly and we read the statement. It is a claim about disclosure, not a lab result.

Drinkware Score indexes what brands publish about their vacuum-seal construction and what the public record shows, with attribution — we test nothing and make no health claims. A verdict describes the state of the published evidence about a sealing method, not the safety of any bottle. A sealed, inaccessible component containing lead is a different fact from lead a user can touch, and we keep those facts separate on every page. If a brand publishes new evidence, the page changes — the source always wins.
