Know before you buy
The Stainless King is designed to keep beverages hot for up to 7 hours. For the best results, we recommend pre-heating the mug with hot water for a few minutes before pouring in your drink.
Yes, the screw-top lid is designed to be completely leak-proof when properly closed. You can safely carry it in a bag or backpack without worrying about spills.
Yes, the mug is top-rack dishwasher safe. However, hand washing is often recommended for any vacuum-insulated vessel to help preserve the exterior finish over the long term.
The mug is designed to be travel-friendly, but the integrated handle can sometimes interfere with smaller or recessed cup holders. It is best to check your vehicle's cup holder dimensions if you plan on using it primarily for commuting.
The lid functions as a secure screw-top closure. It does not feature a separate locking latch, but the threading provides a tight seal that prevents leaks during transport.
