Writing brush and ink

The raw materials of the ink are soot.
If you write it on the Japanese paper and dry, you cannot put it out.

The stamp ink made in Japan does not deteriorate, and the color development is good, and the best quality is stable.
As for the color of the ink, red is common.
Even the same red has various red (vermilion).
