Review (4/5): Thick and good quality
This is a good set of gel nail polish. Bottle size is average from other brands I have tried (usually between 6-8 ml), these bottles contain 7.5 ml. Gel is thicker that most brands, which is kind of good and bad at the same time. Good because you can get a great coverage with 2 thin layers. However, it is a little more difficult to apply, especially the white one that is super thick, but you will get a perfect white!
Like any other set that does not come with base and top coat, make sure to get them before trying to use this nail polish on its own. They won't last if not using base and top coat.
Not a fan of bottles that do not include the sticker with the color, just the number, so you either apply it to the bottle and cure them or get some nail watches, cure them and have them handy when choosing colors.
I have not tested the durability of them (it would depend a lot of the quality of your base and top coat and how well you prep your nails). But so far, I am please with the texture and color set.
