Professional products yield professional results. You won't find metal files in our kit. We vetted hundreds of files, nippers, pushers and oils that veteran Nail Salons would envy. That nipper you bought at the discount store doesn't work you say? No need to tear off your cuticles anymore with a sub par nipper. Ours is professional and sharp but it cuts hang nails easily. A manicure preps the nail for polish and nail art. If you can do this then you will have a salon worthy manicure that will support regular nail lacquer for about 5 days.
