★ REINFORCED NAILS - Our nail care pen greatly supports your nails even with cracked and brittle nails. The serum ensures optimal moisture supply and long-term regeneration. ★ UNIQUE OPERATION - The nail matrix technology in the nail care pen ensures that the nail is opened at the cellular level in the first stage. This allows the nourishing active ingredients to reach the nail fungus to the root of the nail where it rises and to fully develop their effect. ★ EASY TO USE: File the nail with a file and remove porous and brittle areas. Moisten the brush by rotating it on top. Then apply the product to the affected area and surrounding area. Leave on until completely dry. ★ Tested formula: all our products are developed in collaboration with doctors and pharmacists. They are therefore perfectly fit and safe.
