Mavala Scientifique K+ Nail Hardener, 5ml

The tip of the nail is the most fragile part, which breaks easily. It is, therefore, the one that must be strengthened. Mavala Scientifique, created in 1958, is the world's first penetrating hardener. It hardens the cornea plate, welding together the three layers that make it up. Combats soft and peeled nails.
