If you’re a woman, then you’re probably familiar with the whole struggle of painting your nails. Nails take a lot of grooming. You first have to choose a color, apply enough coats that it won’t chip throughout the week, and then sit there and wait forever for it to dry. That’s if you’re lucky and you don’t get nail polish on your clothes. Sure, going to a salon and getting them done is a lot easier, but, honestly, unless your Paris Hilton, you probably don’t have the money or the time to visit a salon every time a nail chips. That’s why I think this could be a great invention.
