I had my first extreme nail biter! I had to use tips because I wasn't confident enough to do sculpts. I hope these stay on... she had very sturdy nails. They were just really REALLY short. I had to use Bio's 2003 Nude as a cover up. Otherwise I would have just left that part clear. I really hope she doesn't chew these off... they're way too cute (and she paid way too much) to just chew them off in a week!
