Best top coat ever. It bonds to the nail polish and makes nails super shiny. The only thing that takes getting used to is the thickness, try to use as few strokes as possible and get plenty on the brush when you dip. I did this on one half of my nails and went to bed. My other nails had tons of pillow fabric lines, the seche nails were perfect! Buy it at most beauty supply stores, you’ll be hooked.
