Nail Art Pens Which Work?

     I am a nail art fanatic.  I love the art as well as the small tiny details.  Not all nail technitians like nail art.  I always use different brushes and other impliments to do my nails art.  Recently I bought a nail art pen as Wal-Mart.  Yes Wal-Mart, I bought two Sally nail art pens.  They were tranlucent and not at all what I was expecting.  Then I saw an ad in Nail Pro magazine.  The ad was for nail art pens made by Cina.  They only offer a few colors which are: Purple, black, pink, red, and white.  I bought a Cina white nail art pen when I was shopping for supplies at Sally's.  I then took it to school and did a french manicure with it.  Although I was not using my brushes which was weird, I used this pen and the consistency as well as the polish itself was fantastic.  The polish was not translucent, the polish dried faster than if I had used a brush, and it was quick!  So to all the nail technitians out there, DO NOT BUY Wal-Mart nail art pens.  For less money you can go to a salon supply store and buy one of these pens and you will get what you were expecting.  The pens at Wal-Mart are horrible!
