The paint on the smartphone case has come off ...?

The paint on the smartphone case that I had originally attached has come off. And for the "card stand case", the peeled paint sticks to the adhesive surface. After just 15 minutes of trial, it's no longer usable. I'm disappointed.

On the adhesive surface of the "card stand case", the paint on the peeled smartphone case is sticky.

If you look closely at the package, it says, "There may be some glue left when you remove it. Also, please note that the paint and stickers on the case and smartphone may come off." After all, you have to read the notes in advance. Anyway, it is a convenient product, so if you are using a case or smartphone that you do not have to worry about the paint peeling off, or if you can peel it off a little, please try it.
