If it was an acrylic nail, I don’t know how you managed to gnaw on your finger hard enough. But unless your regular nail is cracked, just super glue it and paint them a solid color.
@ragingloli: Don’t jump into someones question just to judge others, it’s childish. No one cares what you think about women’s nails here. Offer something, or shut the hell up. Acrylic nails and other types of artificial nails have practical uses as well. I know someone who has no nail on her left ringer finger, for her wedding day she had an acrylic nail applied to mask it. Would you rather have the little slut have no nail on her ring finger?
Not to mention they can be used to aid someone in breaking their nail biting habits, and protect the nail bed from ripping or other damage from weak nails breaking which can be extremely painful.
I had mine done pretty regularly when I was 12–15, for those reasons. Does that make me a slut?
