How to refill a Kakimori & Inkstand rollerball pen
What you need:
・Rollerball pen
・Bottled ink (Kakimori or Inkstand pigment ink)
・Tissues or soft, clean cloth
Step 1: Remove the converter
Remove the converter by taking apart the rollerball cap, barrel and nib.

Step 2: Draw the ink
Twist the knob counterclockwise to lower the internal piston completely.
Submerge the tip of the converter in ink and twist the knob clockwise to draw ink into the converter.
*Ink must be refilled directly via the converter — refilling through the nib may cause damage to your pen.

Step 3
Wipe off excess ink from the converter and insert firmly into the nib.
Allow a few minutes for the ink to reach the nib — if ink fails to flow, apply a tissue to the nib and shake lightly.
