    I’ve been using this base coat/nail hardener for one month straight and I can’t believe how much it’s transformed nails. They’re noticeably stronger; I could never grow my nails out without at least one breaking! This is a MUST HAVE for all you DIY ladies that give yourself manicures. I always wear polish with a glossy top coat for protection.

    Awesome products!

    London town has proven the point. I’ve now gotten rid of all my other nail polish topcoats space coats, and just strictly use London town. They are fantastic. From their price point to the product safety ingredients to actually working. Oh my gosh what more can you want?

    Great base. Keeps my nails polish on without chipping for about a week! The pic is 5 days and going strong.

    Works great

    Been using it for a week and it's keeping my nails from breaking and lifting. Also dries really quickly.

    Love the product

    Which of you should be asking about the regular nail Hardner I saw it on Facebook bought it to try it. It’s the best I had to use on my nails after being with gels off I have ridges but not with your polish.
