New, Unused January 2026, in Hawaii I do not conduct transactions with those in Hokkaido, Okinawa, Tohoku, or remote islands. (I have selected a shipping method other than Mercari delivery. If shipping to the above areas is required, the shipping fee will change, so please be sure to inform me.) Made of durable, rust-resistant kitchen-grade 18/8 stainless steel. Excellent insulation with a double-walled vacuum construction that keeps drinks hot or cold for a long time. Dishwasher safe. Fits in most cup holders.
