Side one: File – perfect for getting your nails to your preferred shape. Square or rounded, this is the side to use to shape your nail.
Side two: Buff – run this side along your entire nail to help buff away any ridges or peeling. Take care not to overdo it though, as excessive buffing can damage the nail.
Side three: Polish – uses a finer buffer to help smooth down the new nail surface and reach any tiny imperfections missed by the buffing step.
Side four: Shine – the final step works to leave a beautiful sheen on your nails so that they’re ready for a slick of polish!
