Kinto Travel Tumbler.

Sleek and durable, consider this tumbler your new commuting companion. It has a double-walled stainless steel vacuum canister that keeps your drink hot or cold for up to six hours, while preserving the subtle aromas and flavors. An electro-polished interior prevents odor and stains meaning you can switch between your cold brew, oat milk flat white and green tea with no undesirable side effects. Leakproof, scratch-proof, and built to last.
