Mavala Stop 10 ml

I bought it for my son as a help to prevent him from biting his nails. The taste is bitter, but it works if applied consistently for a certain period.

It is only useful on the first day of application; after that it serves no purpose. It comes off very easily.

Works for the purpose

My daughter, since she started using it, no longer bites her nails and says she feels very well; in fact, they have even grown. Occasionally, by mistake, she tasted the nail polish and said it had a horrible taste, so it works well and we highly recommend it.
