Tempered Glass is up to five times stronger than regular glass. It is heated and cooled quickly. The process makes the glass break differently. It will shatter rather than break in shards. It's a safety feature and is used many applications. Most cell phones are made from tempered glass. The additional tempered glass case provides an added level of protection. In many cases of being dropped on hard surfaces, the case will shatter but the screen will be intact. You will still be able to use the phone.In addition to being stronger, most tempered glass screen protectors have a silicon film coating that is resistant to oil from fingerprints as well.
This tempered glass screen protector is compatible with iPhone models 5 5S and SE models.
