Tweezerman Neon Filemates are high-quality, professional nail files for expert nail shaping and filing. Neon Hot Filemates come in a 3-pack. Key Benefits: Dual-sided professional nail file with 100/180 medium and fine grit surfaces for filing natural and acrylic nails. Comes with a convenient carry case to keep files clean and protected. How to use: Always file nails in one direction instead of back and forth to prevent nails from splitting. Use the coarser side (100 grit surface) to shape nails. Also great for sanding and filing acrylic nails. Use the finer side (180 grit surface) to smooth nail edges. Replace nail files after three months of regular use.
