Is it really leak-proof?

Yes. Follow four simple steps before heading out and your cup won't leak. See the full checklist in the Care Guide.

Why ceramic interior? What's the difference?

Stainless steel interiors can affect taste over time. Ceramic doesn't interact with your drink, no metallic taste, no absorbed odours, easier to keep clean.

Are the materials safe?

No BPA, no lead, no heavy metals. 18/8 grade 304 stainless steel, copper-lined walls, ceramic interior. Tested to LFGB, the EU food-contact standard.

How does it stay hot (or cold) for so long?

Double-wall insulation with a copper lining between the walls. Copper reflects heat back into the drink.
