OPI

I really like the OPI nail polish. There are lots of different pretty colors so I can make a big variety of designs on my nails. Thanks for the quality!

I am slightly biased as I am an O. P. I nail varnish addict I have sooooooo many colours, it is the best in the world. The only other which in my opinion can stand with it is Chanel (I lurve Rouge Noir).
O. P. I goes on perfectly, easy to add coats on top of others. Gives you a great hard shiny look. The matte coat clear is cool.
The varnish stores well for YEARS I have kept bottles for over 5 years which still went on well.
I like to match colours with my clothing, I am ocd so my nails have to be perfect. I find it is best kept in the fridge in hot weather or it bubbles on your nails. I moved from the UK to Spain so that is how I found out.
Best colour range.
I cannot speak for the gel or glitter stuff, or the false nails, as I have never used any.
I prefer my nails to be long and real.
Yes buy buy buy... but not if you find it really cheap, the Chinese sell a nasty cheap fake O. P. I on Ebay. Expect to pay around £12 or more for a bottle. Okay I am going to lovingly fondle my collection of O. P. I now as due to another brand which damaged my nail beds, l cannot wear my beautiful nail varnishes.

I personally am a huge fan of OPI nail polish. The quality of the polish is excellent and the huge variety of countless colors is just beautiful.
