We wouldn’t want you to wash your mouth out with soap to stop cursing, and we wouldn’t recommend ingesting harsh-tasting chemicals to teach you a lesson about nail biting. It’s much more humane to change your habits by keeping a nail file on hand, and using it to smoothen rough surfaces the moment they happen. We love the size and cute-ness of Tweezerman‘s Super Kawaii Matchbox Itty Bitty Nail Files ($5, at Sephora). They’re small enough to hide in the pocket of any purse or pant, and put a positive spin on a disappointing snag.
