Nail Polish Usage
Estimate how many manicures a nail polish bottle provides.
About Nail Polish Usage
Each manicure uses coats multiplied by polish per coat, and the bottle size is divided by that amount. Polish thins with use so it looks like it lasts forever, but the count still helps reordering decisions.
