For neat, shiny nails on a budget and I mean that! 1 nail buffing block or stick can last you a year at least. So everyone can have beautiful nails all the time if they just make the effort to. I used to do this when I was younger as schools have strict no nail polish policies.
It's a 3 step process of shaping the nails, filing away ridges on the nail surface, then buff those nails until you get that shine! So natural, guys can do this too.
