Diami Micro Washable File 400 Grit 

DIAMI Micro Washable File is made up of a film texture, not stone powder, so you can file your skin and surrounding areas safely and in a clean manner. Because there are no vibrations with this filing technique, you can file your cuticles and side skin with no stimulation. This file is suitable for those who have sensitive fingertips and/or weak fingernails. It can also be used to smooth out rough surfaces on your nails and/or control the length of your nails. The surface of this file can be cleaned with a wet wipe, so it can be reused cleanly for a long period of time.
