Uses a much thinner sponge than the conventional Kamiyasu!
While retaining the same characteristics, it now conforms better to curved surfaces!
An ultra-thin sponge file with a thickness of just 1mm.
Uses the same highly durable cloth file as the conventional product.
The thinner sponge allows it to conform to curved surfaces better than conventional Kamiyasu files, and is firmer than paper or cloth files, providing an exquisite feel. The
sponge surface is printed with a grit that makes it easy to see at a glance.
The printed area uses ink that does not bleed easily, so the ink does not dissolve easily even when sanding with water, allowing you to work with confidence.

Uses a 1mm thick sponge that is easier to follow curved surfaces than the thinnest 2mm sponge.
Set of 6 sizes: 240, 320, 400, 600, 800, and 1000
