Water-removable nail polish. Application: 1. Apply a thin layer of nail polish to clean nails. 2. Wait about 5 minutes. 3. To remove the nail polish, simply wash it off with warm water and a sponge. The nail polish has a deliberately bitter taste, which helps reduce the habit of nail biting. Warning! Do not put your fingers in your mouth and do not eat it. If an allergic reaction occurs, rinse thoroughly with water and discontinue use. Use only under adult supervision!.
