What are the benefits of using silicone cup sleeve for thermos cups?

Nsulation: The water cup cover can play the role of heat insulation after being pressed.

Anti-slip: The water cup cover, especially the silicone, can effectively increase the friction of the outer wall of the water cup to achieve the purpose of anti-skid.

Heat insulation: the water cup cover can effectively isolate the heat of the water cup after pouring hot water to prevent the user from being burned.

Beautiful: The water bottle cover can be made in various shapes, and can be designed in various colors to eliminate the monotonous characteristics of the glass and increase the aesthetics.

Protection: The water cup cover can also protect the glass from abrasion or breakage, and has a certain anti-fall protection feature.

If I want to be shatter-resistant, I can only say that the original poster thinks too much of the cup sleeve. The force of the cup to fall from a height is very strong. Since you buy a glass, you must have the consciousness of breaking, 100% fall-resistant. Secondly, the cup sleeve will increase the cost intangibly, because the cup sleeve and the cup are usually not produced in the same place, which is very convenient.
