Insulated Tumbler with 360 Lid - Leak-Proof Stainless Steel Coffee Cup

Our high-quality Tumbler boasts exceptional temperature control, thanks to its double-wall vacuum insulation, insulated layer inside the lid, and copper coating. This ensures your hot beverages stay toasty for up to 6 hours, while cold drinks remain chilled for up to 12 hours.

Leak-proof and sweat-free, the easy-to-open and close lid with two silicone rings provides a secure seal, preventing any leaks or spills. This makes our tumbler the perfect insulated travel mug for on-the-go use, whether in your backpack or bag.

Featuring a 360-degree twist cap with three positions (locked, drink, opened), our thermos coffee mug is incredibly convenient to drink from, without the worry of any leaks.

Crafted using high-quality 18/8 stainless steel, food-grade plastic, and food-grade silicone, our products are rust-free and BPA-free, ensuring your safety and peace of mind.

Designed with convenience in mind, our leak-proof stainless steel coffee cup with a screw-on lid has a wide mouth opening, making it effortless to clean. Plus, it fits perfectly in car cup holders.

We are so confident in the quality of our products that we offer a 5-year manufacturer warranty. The stylish, award-winning design and exceptional quality make our stainless steel coffee cup a perfect gift for Christmas and a must-have for your home.

We have conducted over 100 tests to ensure our Tumbler keeps liquids hot for up to 6 hours when filled with boiling water. According to our measurements, after 6 hours, the temperature of your drink will be 127°F if the thermos is still full.

The more content placed in the thermos, the longer the original temperature will last. For best heat retention, we recommend preheating the tumbler with boiling water before pouring in your hot drink. For cold drinks, pre-chill with iced water before adding your chilled beverage.

All our products are dishwasher safe. However, we advise against using alkaline dishwasher products to prevent any potential damage. Alternatively, you can easily clean the tumbler using a sponge, thanks to the 3.31-inch mouth diameter, which allows you to reach all areas.

Our thermoses are made of high-quality stainless steel (ANSI 304 2B - 18% chromium and 8% nickel) designed for corrosion resistance and safe use as a food industry product. They also feature food-grade plastic and food-grade silicone, and are all BPA-free.

The Tumbler weighs 0.73 lb, with a base diameter of 2.76 inches, a mouth diameter of 3.31 inches, a height of 6.42 inches, and a height without the cap of 5.43 inches.
