MAVALA STOP PENCIL has been specifically designed to help put an end to the habit of putting fingers in the mouth and biting nails and cuticles, in addition to recovering and maintaining beautiful nails. It is an applicator pencil with the tip moistened with a bitter-tasting aqueous solution, enriched with a botanical extract that nourishes the cuticles. The nails and their contour will regain a beautiful and well-kept appearance. A practical and nomadic format to take everywhere. Tips for use Apply the product using the felt tip on the tips of the nails, with or without polish, and on their contour and wait for it to dry. Repeat 2 or 3 times a day if necessary until the habit of putting your fingers in your mouth has ended. Avoid washing your hands immediately after application. Avoid touching food with your fingers, so that the bitter taste is not transmitted to the food (use cutlery or gloves).
