Upgraded nail biting polish for nail biters, designed for kids and adults, features an innovative bitter flavor technology that significantly increases bitterness. This stop biting nail polish helps children reduce unconscious finger biting behavior and supports the development of healthy habits. Instant results with taste memory effect: Apply a small amount of nail biting polish to fingertips. The unique bitter taste instantly activates taste buds, creating a quick association between biting and bitterness, helping discourage nail biting in children.

Optimize your experience: This anti nail biting polish features an advanced formula. The bitter taste lasts up to 3 days with a single application and dries in 1 minute. It is water-resistant. Reapply when the taste fades or if peeling occurs to maintain effectiveness. Quick-drying thumb sucking nail polish: Apply easily with the included brush, just like regular nail polish. Dries in 30 seconds to a non-stick, invisible finish that stays intact even after hand washing. Safe for ages 3 and up. Suitable for both children and adults. Easy to incorporate into daily nail care routines to help prevent thumb sucking and nail biting.
