Kitchen Oil Proof Wall Sticker Clear Self-Adhesive Film Covering Removable Protective Film Shelf Drawer Liner Decor

I've bought this kind of film before (for the wall next to the stove), it holds well, but it arrived broken in half, I don't know how it will hold in the bent place, so I removed one star.

It doesn't stick at all, no matter how much I try, but it's called SELF-ADHESIVE. I contacted customer service, but there's no answer yet.
