easy to apply - just be sure of placement, because they really do stay in place. quite large, so be careful of size and where you want them -- no returns to this vendor. and they didn't have them in smaller sizes like KreativeDecals (used to offer them on Amazon, but no longer). I started to post a less positive review because of the size and no returns, but honestly they are great quality and beautiful design -- I'll put them on an exterior wall as a mural
