IT WORKS [SEP] This definitely works the best. I have tried every nail Hardner on the market, I have even taken hair skin and nail vitamins which did not work. My nails are beautiful now, longer, harder.  I do not go to the salon, I do my own nails, I use Color Street nail stickers.  I have used Color Street for three years now and every morning I put a fresh coat of this nail Hardner on and my manicure stays intact for three weeks, and no, I don’t have a dishwasher, so I’m doing dishes and cleaning and my nails still look beautiful. 😀 I get compliments all the time.
