How to change the ink colour

To change the ink colour while keeping the same nib, simply rinse it with water. To switch to ink from other brands or to completely change colours, we recommend replacing the nib.

Step 1: Rinse with water

Remove the converter. Following the same process as Step 1 above, detach the nib from the grip section. Rinse any ink residue from the nib under running water, pointing it downwards and flushing it with water. Clean the converter by drawing water in and out, as you would when filling it with ink.

Step 2: Soak overnight

Fill a cup with water and soak the nib overnight to a day, then rinse again under running water.

Step 3: Remove excess water

Press a tissue against the nib and shake well to remove any remaining ink and water.

Step 4: Fill with ink

Attach the nib as described in Step 2 of How to change the nib above.
Fill the converter with ink and allow several minutes for the ink to flow. Since cleaning with water does not fully remove ink, some mixing of colours may occur. Kakimori inks can be mixed without any issues.

Troubleshooting and maintenance

Extended storage

For extended storage of a removed nib, we recommend cleaning it first with the Kakimori ink cleaning solution.

Step 1: Soak overnight

Remove the nib from the grip section and place it directly into the bottle of the cleaning solution, pointing downwards. If the nib floats, close the cap and gently shake the bottle up and down until the nib is fully submerged. Leave to soak for 9-12 hours.
