Negative Positive
Title: worked in one day
Review: My 4year old bit his nails non-stop. I told him the mavala was a special magic potion. I was shocked he let me paint it on. It only took a few times putting his fingers in his mouth before he stopped. He didn't even complain about the horrendous taste. My one year old accidently got some on his tongue and it made him vomit. A few weeks later I saw my 4year old try biting his nails again and i painted on the malvala and he hasn't put his fingers in his mouth again. It really truely worked.
