longleage Nail Cleansing Scrub I am also selling other Longleage products, so please take a look if you'd like. New, unused. This is a fine-particle nail scrub that gently and softly removes unwanted dead skin cells remaining on the nail surface with plant-derived cellulose. By removing dirt from the nail surface, dullness disappears, and you get transparent, beautiful nails. It also enhances the penetration of the serum applied afterward.
