What is a tumbler?
A tumbler is generally a water container made of ceramic or stainless steel with a vacuum layer. The top is covered and tightly sealed. The vacuum insulation layer can delay the heat dissipation of liquids such as water inside to achieve the purpose of heat preservation. The inside and outside are all stainless steel, refined with advanced vacuum technology, elegant in shape, seamless inner tank, good sealing performance, and good heat preservation performance. You can put ice cubes or hot drinks.
Advantages of tumbler:
1. Good heat preservation effect. The stainless steel double-layer high vacuum heat preservation technology is used, which can isolate the influence of the outside world on the water temperature.
2. Lightweight and portable, thanks to vacuum technology, the weight of the tumbler is very light.
3. It is resistant to falling, using a metal shell, which is strong and resistant to falling.
