What criteria do my nail polishes need to adhere to for me to consider them a great product?

1. Colour Selection - Essence has this down. From Mauve browns to glitter pinks and neon blue...they have it all.
2. Price - it is only a nail polish, not an Ipad...These items are extremely affordably priced.
3. Quality and lasting power - These apply fully opaque for the most part with a few formula misses here and there on some of the very milky, light colours such as yellow. It lasts longer on my nails than some of my more expensive brands.

This is a great product and Essence has an amazing variety when it comes to nails products such as tools and more.
