Amazon has this Electric Manicure 5-Piece Nail Kit for $3.82 with FREE shipping right now.
It comes with 5 different types of files and a carrying case.
The reviews on this are a bit mixed, but many people say it works awesome. I figure it can’t hurt to try it at less than $5, and if you like it you’ve got a nice little electric manicure set at home when you need it.
Thanks, SwagGrabber.
