Black File 100/180 — the all-rounder nail file for the studio
The black file with 100/180 grit is part of the basic equipment of every nail designer. In the trade, this grit is often referred to as the all-rounder: the coarser 100 side is suitable for removing material and shortening gel or acrylic enhancements, while the finer 180 side is for shape corrections and reworking the surface. Anyone searching for "nail file 100/180" or "grit 100/180" ends up exactly at this classic.
The shape combines a curved side with a straight one: with the curve, you follow the side nail edges and the nail fold, and with the flat side, you neatly refine flat areas. The abrasive grain is durable and designed for daily use in the studio.
A practical tip from professional practice: slightly dull the edges of a new file before first use by briefly running it over an older, used file — this avoids small skin injuries from the sharp file edge. For enhancements, refills and daily shaping of artificial nails, this file is the reliable standard tool.
