Is there a tempered film on your watch?

Tempered film is glass film. Glasses on watches are mostly synthetic glass, mineral crystal glass and sapphire crystal glass. The common mobile phone film is PET plastic, which is different. Generally, a dozen pieces of tempered film are cheap, and hundreds of expensive ones are normal. It's normal to be cheaper than ordinary movies. After all, some plastic films are also expensive. Toughened film is not easy to foam and easy to attach. Taobao can be bought and pasted by itself, but it is much thicker than plastic film, so it will affect the touch sensitivity of mobile phones to some extent. The answer comes from Global Plastics. If you think it is feasible, please adopt it.
