Elemental
Elemental leans into a genuinely uncommon feature: a hand-glazed ceramic travel lid, so the surface you drink from is ceramic rather than the plastic used on nearly every other travel mug. The only soft part in the seal is a removable silicone plug, which keeps the mug spill-resistant. That puts their ceramic-lid tumbler in the silicone-only tier, and ahead of ceramic-lined mugs that still cap off with a plastic lid.
How clear are their specs?
Names hand-glazed ceramic lid and a silicone plug, but is light on the exact interior lining and body construction detail across sizes.
Lead testing disclosure
Product pages state general "FDA, Food Grade, and Prop 65" compliance for the tumbler, but this is generic regulatory-compliance language, not a lead/cadmium-specific claim - notable given that the hand-glazed ceramic lid is exactly the kind of part (a glaze) where lead disclosure would matter most. No named lab, test numbers, or dedicated safety page for the ceramic glaze were found on elementalbottles.com.
