An ultra-thin swamp file that can be used by attaching it to a mechanical pencil.
Perfect for adding detail to molds and scribing lines.
It can get into narrow gaps that were impossible with regular files.
Made in Japan.

The file has diamond coating on both sides (top and bottom). The diamond coating will gradually wear off with use, so if it starts to feel like it’s not filing properly over time, please use the other side.
*You can also use a regular mechanical pencil.
