Stainless Steel Coffee Tumbler - Vacuum Insulated, Travel Mug, Dishwasher Safe - Keeps Hot for 8 Hours

Product Description Does It Really Keep Beverages Hot for 8 Hours? Yes, it does. We have conducted over 100 tests to ensure that our Tumbler can keep liquids hot for up to 8 hours when filled with boiling water. Based on our measurements, after 8 hours the temperature of your drink will be 127°F if the thermos is still full.

How to Keep the Temperature Consistent? The more content you place in the thermos, the longer the original temperature will last. For best heat retention, we recommend preheating the tumbler with boiling water before pouring a hot drink, and for cold drinks, pre-chill with iced water.

Is It Dishwasher Safe? Can I Fit My Hand in the Tumbler to Clean It? All our products are dishwasher safe, but we suggest avoiding alkaline dishwasher products to prevent potential damage. Alternatively, you can clean the tumbler using a sponge and take advantage of the 3.31'' mouth diameter to easily reach all areas.

What Is It Made Of? Our thermoses are made of high-quality stainless steel (ANSI 304 2B - 18% chromium and 8% nickel) designed for corrosion resistance and safe use in the food industry. They also include food-grade plastic and food-grade silicone, and are all BPA-free.

How Much Does It Weigh? What Are the Dimensions and the Base Diameter? Weight: 0.87 lb. Base diameter: 2.76''. Mouth diameter: 3.31''. Height: 8.19''. Height without the cap: 7.2''.
