Discourages nail biting and thumb sucking. Nail biting is a nervous habit, which can rapidly become uncontrollable. It has a bitter yet harmless taste and the appearance of clear enamel. Helps break the nail biting habit and thumb sucking. Works for children (more than 3 years old) and adults. To use without or over your nail polish. Also recommended for children but not under 3 years old, as their taste buds are not fully developed and they might get used to the bitter taste.
