Use

We invite you to read our Kakimori Use + Inspiration blog for step-by-step instructions on how to use, clean, and maintain your rollerball pen.

Unscrew the pen barrel from the grip section.
Remove the included ink converter from the pen body, and twist the knob counterclockwise to fully lower the internal piston.
Submerge tip of the converter in the ink, and twist the knob clockwise to draw ink into the converter.
Wipe off excess ink, and insert firmly into the pen's grip section. Allow a few minutes for the ink flow to reach the pen's nib.

Care

Daily use is recommended to prevent the nib from drying out. When traveling by plane, we suggest filling with ink after your arrival to prevent leakage during the journey. We recommend using Kakimori's Ink Cleaning Solution when switching between ink colors.
