Nail biting is a bad habit that affects a large part of the population. This habit can quickly worsen the appearance of nails and their contours. MAVALA STOP PENCIL has been specifically designed to help end the habit of putting your fingers in your mouth and biting your nails and cuticles, and to restore and maintain beautiful nails. It is an applicator pen with a tip moistened with a bitter-tasting aqueous solution, enriched with a botanical extract that nourishes the cuticles. Your nails and their contours will regain a beautiful and well-groomed appearance. A practical and portable format that you can take anywhere. Directions for use: Apply the product using the felt tip to the tips of your nails, with or without nail polish, and to the nail contours, 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 is eliminated. Avoid washing your hands immediately after application. Avoid touching food with your fingers to prevent the bitter taste from being transferred to the food (use cutlery or wear gloves). Note: For children (over 3 years old) and adults. The product's effectiveness may not be effective for younger children, as their taste buds are not fully developed and they may not find the taste of enamel unpleasant. Contains 72% ingredients of natural origin.
