Mavala Stop

Mavala Stop discourages nail biting and thumb sucking. Nail biting is a nervous habit, which can rapidly become uncontrollable. Mavala Stop has a bitter yet harmless taste and the appearance of clear enamel. It helps to break the nail biting habit and thumb sucking. Works for children (more than 3 years old) and adults. 
Apply a coat over the entire nail (or polish) and allow to dry. Repeat the application every two days. Continue the treatment until nail biting has ended. Never wash hands immediately after application.
