Gululu Ice Ba Thermos Flask

The Gululu Ice Ba thermos flask is made from 316L antibacterial stainless steel. This material has been tested to kill 99.9% of E. coli and Staphylococcus aureus, and it is resistant to acid and alkaline substances, making it less likely to retain tea or coffee stains. It can hold drinks like cola, juice, and lemonade without corroding the interior.

The flask body uses a multi-layer structure to lock in temperature: the innermost layer is the 316L inner layer, surrounded by a copper-plated layer that helps reflect heat. In the middle is a high vacuum layer that interrupts heat conduction, and the outer layer is made of 304 stainless steel with a scratch-resistant paint finish. This design allows both hot and cold beverages to be maintained for an extended period, making it suitable for enjoying hot tea in winter and cold drinks in summer with the same cup.
