This is the last nail file you need to buy. Do yourself a favor by replacing those sandpaper disposables with Tweezerman's 3in long Pedro Fina ceramic file. Comes in its own plastic carry case with pocket clip, about the size of a large pen. It's sturdy enough not to get broken or lost in any bag, and one end is tapered for cleaning under dirty nails. The best part is the triangular design, consisting of two flat surfaces with little lips on the edges and a third concave surface. Unlike the traditional flat file, these contours make it easier to file around shorter nails.

I have one in my office, my car, my handbag, my home computer desk, bathroom, bedroom...
