It's always a good idea to use different types of protection for your devices to avoid annoying pocket scratches or larger tears. Here's a really good deal on a protective film for the back.

This protective film for the iPhone 12 Pro Max, acts as a thin extra layer and protects the back of your phone from the well-known pocket scratches that typically occur when, for example, your phone and keys are together in your bag or pocket.

In addition, the film also protects against the accumulation of dirt and grime. This way, you can get protection for your phone without the need for a case if you don't want it.
