Description Nutritive Nail Cream to Stop Thumb SuckingStop putting fingers in your mouth with our deterrent treatment nail polish. Works effectively for kids or adults to help allow nails to grow healthier and discourage putting fingers in your mouth. Stop Bite Nail CareOur nail biting polish owns natural ingredients, such as Almond Oil, Grapeseed Oil, Lemon Oil, etc, to stimulate nail growth and promote nail repair, which helps the nails keep healthy and look good. Moderate Bitterness That Works Just RightNot too bitter to make you sick yet bitter enough to discourage you from biting your nails (or putting fingers in the mouth) ever again. The amount of the bitter substance in the product is carefully measured to suit the taste buds of most people. Easy to ApplyIt adopts 2 in 1 design and each attaches a brush to the bottle cap, so you could conveniently use the brush to apply a layer of this nail polish to the nails. ApplicationThe bitter taste will stay on your nail/finger for several hours and will not rinse off after one or two normal hand washes. However, if you really want to get rid of the bad taste immediately (such as before eating your meal), a thorough soap wash will rid your hands of the product. For children over 3 years old
