I have the black one called eternity , i find it to be some crap considering my nails are short. I don't see much of a crackle effect. It dries pretty fast and it smells like gasoline. Idk but i don't like the smell at all. I will try to grow my nails long and try again with this polish. As u can see the bigger your nail the crackle seems longer and bigger but if ur nail is short it look like 3 lines.
