first bought this back in 2017 and still easily my favorite "trick." endless compliments every time i finish my nails with this pretty pixie dust. idk if this is incorrect, but i use it over regular polish all the time. the consistency of the chrome effect depends on applying it at the right tackiness - too wet and it'll smush into the base, too dry and only a few flecks will stick, but really very easy to use. love love love this stuff, please never discontinue it 🩷🧡🩵💜
