"iro-utsushi" is a dip pen type writing instrument that writes by dipping the nib into fountain pen ink. Unlike typical dip pens, it has a nib point similar to a fountain pen, so it has a soft touch on the paper and allows you to write fine letters and draw illustrations smoothly.
In addition, you can easily enjoy various ink colors by rinsing the nib with water and wiping it with a cloth.

The pen nib has a guideline engraved on it, making it easy to see at a glance where to dip it in the ink.

- Before use, dip the pen tip in water and wipe it with a cloth.
- Use the line on the pen tip as a guide to dip the pen in ink.
- If the barrel becomes stained with ink, wipe it with a cloth.
- When changing ink colors, wash the pen tip with water, wipe it with a cloth, and then use the next ink.
