I bought this set because I like "natural" paint my nails and just wanted to increase durability. Instead purchased the expensive competitor, I wanted to first test the much cheaper alternative of Bluesky. Unfortunately, this set is "colorless" for but absolutely not suitable. The durability is not promising - you can paint without any effort from the nail scratch, although I've had 2 layers Base Coat and Top Coat cured for 2 min.. And what's worse: the paint discolored natural nails yellow !! I have never had problems with discolored nails, but after only 1 day caught the verfäben and after 4 days saw my nails like those of a strong smoker. I then scraped down the paint or deducted and yet ordered me the original. Perhaps staining of natural nails with color paints is not so bad - but I can neither judge nor I will try out this because of my experience.
For colorless I can not recommend the coatings absolutely! ! And stable are not the nails and the durability is also bad.
