dragonbone 5 These are the first foils I have ever tried. I use them with gel polish glue.I am not very good at manicures, but they came out beautifully. My left hand foils are a bit grown out, (see photo) as they are already a month old. I just painted over with clear gel to refresh and strengthen them. My right hand lasts about one week to 10 days, depending on how rough I am.To make them last, it’s important not to go right to the edge, and to refresh with gel nail polish every few days.
