It's annoying when a sticker breaks in the middle while peeling it off lol

It would be nice if it fell cleanly in one go.
It always tears in the middle...
Scratching the remaining stuff with my fingernails
It's getting even messier ㅠㅠ
I was thinking of melting it with a hairdryer to pry it off, but I can't because I'm afraid the plastic will melt.
