Collistar is an italian brand that I have never tried before. But it was a pleasant surprise.
Blue jeans is a marine blue creme polish with a very smooth formula. Two layers is enough to get full cover and the result is very good.
The brush holds a lot of paint though so you have to remove a lot before you start painting.
The color is really nice, it is rich and glossy. I do like it, but I have seen it before. But, hey, isn't there dupes everywhere now?
