Set of 2! I bought a lot of these because I wanted to make my room white, but I have some left over, so I'm selling them (⋆ᴗ͈ˬᴗ͈)” I re-applied them many times, but the adhesive is very strong, and they didn't peel off, which was great. Although they are strong, they don't damage the original wallpaper. I was able to use them for things like remodeling my desk, closet, and kitchen! The color is a pure white with absolutely no yellow tint! (。・ω・。) Instant purchase is OK.
