I was surprised when it encouraged a topcoat since there are little gems, but I couldn't tell a difference once it was added and felt better about the decals staying on longer. I stared at these non-stop, they really grab a line of vision! I wore them for a good solid four days when some of the edges started coming up. But with shower, dishes and the like, I thought they held up nicely. The adhesive was pretty strong I felt kinda queasy pulling them off, but remover took the remainder of the glue fine. I really liked these for a quick, elaborate looking nail design and would purchase them again!
