The good thing about this is that it actually works. This extends the life of my polish to at least three days without chipping, no matter what I'm doing with my hands. I could be washing my hair, doing dishes, gardening... my polish won't chip. The bad thing about this is that it takes two digit number of hours to dry. Literally. God forbid I apply this sometimes in the afternoon, I'll wake up with sheet marks on my nails the next morning.So if you're going to use this, make sure to apply it sometimes in the morning, be careful with your hands for the next three to four hours (yeah I know) and if you manage to that you'll be super happy with your polish for the next three days. Or get a Shellac.
