STTOKE was born in Australia with the desire to eliminate disposable cups. Winner of the GOOD DESIGN AWARD, STTOKE is not only attracted by its design. The outside is stainless steel (vacuum insulated structure) and the inside is ceramic coated. Thanks to this coating, metallic odors are shut out and the original taste and aroma of the drink is preserved. Exhibits a high heat and cold insulation effect (heat insulation 3 hours and cold insulation 6 hours), For L size and grande size, a completely watertight lid is adopted. It does not leak even if you put it in a bag, so you can use it as a tumbler or a water bottle. The smooth curved design makes it easy to fit in the hand and easy to drink with a small tilt. In addition, the wide mouth makes it easy to wash and is suitable for drinks such as lattes. The bottom of the STTOKE is inlaid with rubber parts that prevent slipping when placing the cup and also help absorb shock. There is no condensation, so you can enjoy coffee during the day and beer at night!
