ForPro Super Quick Shine 2-Way Buffer has a silk-like surface that provides high-gloss shine to natural nails. It makes a great manicure and pedicure tool as the spongy foam of these double-sided nail buffers allow abrasive material to flex and eliminate dull ridges. The green 400 grit gently buffs nails and removes ragged edges while the white 4000 grit shines nails prior to applying gel polish and nail lacquer. The sanitizable nail buffers are hygienic and safe to use - they are washable and sanitizable. They also come individually wrapped in a box of 25. These pedicure and manicure nail files measure 3.5” L x .75” W each and are packed for convenience in a clear, reusable storage container. ForPro Professional Collection features the highest quality, best value, and largest selection for professionals and consumers. All products include 100% unconditional guarantee.
