Portable Vacuum Insulated Travel Coffee Mug

Our Tumbler keeps beverages hot for up to 8 hours, as confirmed by over 100 tests. When filled with boiling water, the drink temperature will be around 127°F after 8 hours. To ensure consistent temperature, it's recommended to preheat the tumbler with boiling water before adding the hot drink, or pre-chill it with ice water before adding cold beverages.

All our products are dishwasher-safe, though it's best to avoid using alkaline dishwasher detergents to prevent potential damage. Alternatively, the 3.31-inch mouth diameter allows easy access to clean the tumbler using a sponge.

Constructed with high-quality 304-grade stainless steel (18% chromium, 8% nickel), our tumblers are designed for corrosion resistance and safe use as food-grade products. The materials also include food-grade plastic and silicone, all of which are BPA-free.
