Review (5/5): Great quality for the price
I enjoy using these because they have pretty good pigmentation, they stay for quite awhile (unless you eat something with a lot of oil) and they don't bleed like a lot of liquid lipsticks/stains do.
The formula was an in-between of a stain and lipstick, the texture was very similar to the KVD liquid lip stains. I can wear these for about 5+ hours with minor eating or drinking without needing to touch up the color in the center portion. I didn't notice any stickyness or tacky residue once dried. When you first apply this is has a bit of an oily feel but it dries pretty quickly. The only con I really have for these is that they have an unpleasant smell, not specifically this set but just the city color lip stains in general all have a weird smell.
Because of the really low cost, pigmentation, longevity, and selection I would choose to buy city color over some other lip stain brands just because they are pretty similar but so much more wallet friendly. I only wish that they would work on the smell of the product.
