Does it really keeps beverages hot for 6 hours?

Yes, it does. We have done 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.

How to keep the temperature consistent?

The more content placed in the thermos, the longer the original temperature will last. Pro-tip: for best heat retention, preheat tumbler with boiling water before pouring hot drink. For cold, pre-chill with iced water before pouring cold drink.

Is it dishwasher safe? Can I fit my hand in the tumbler to clean it?

All our products are dishwasher safe. However, avoid using alkaline dishwasher products to prevent any potential damage. Alternatively, you can clean the tumbler using a sponge, taking 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 as a food industry product; food-grade plastic and food-grade silicone. All products are also BPA-free.

How much does it weight? What are the dimensions and the base diameter?

Weight: 0.73 lb. Base diameter: 2.76”. Mouth diameter: 3.31”. Height: 6.42”. Height without the cap: 5.43”.
