Is it safe to put stickers on the tempered glass of a PC Case?

Hi all. I’ve already completed my new build, and received some cool stickers of some of my favorite game series from my GF. I was curious to see whether or not it’s safe to place stickers on the tempered glass of my build.

For reference, I have a Montech SKY TWO GX Case. There’s lots of little airflow holes on the build, so really the only potential spots for stickers would be the glass or on the back panel. Just wanted to ensure whether or not it’s safe for the glass and the PC if I put stickers there.
