This one’s a savior in a pinch: Forgot your nail file at home? No way to trim those ever-growing nails? Hotels give you some complimentary things, but a nail file is usually not among them. But you know what sometimes is? A matchbook. Go ahead and use it for your nails, we don’t judge.
You may think it’s a fire hazard, but hotel rooms often have complimentary matches for their guests, sometimes with their logo on the box. You can’t keep those nails under control with the mini soap or pen and pad of paper often on a desk, but you can use a matchbook if desperate enough.
