Can be tricky to apply the first time, but worth it
I have worn 5 pairs of these and reused one of them, and keep coming back for more! Every time people see them they ask what salon I go to!
The first time I don't think I applied enough glue or didn't press on them long enough, so they kept popping off randomly and I wouldn't notice until the nail itself was long gone (on the plus side, you don't feel a thing when they are removed, unlike acrylics).
It also can be a bit messy trying to keep the glue from getting on the top of the nail after it squeezes out, so keep a wet cloth close by and wipe a LOT. But all that being said, you get better at it and it gets easier. Now they last me 7 days before I replace them (could go to 10 days I suppose, but my nails grow out super fast). So the finished result of a salon looking manicure for $14 in 10 minutes? WORTH IT!
