Easy Cartridge Replacement Guide

1. Prepare: Click the top mechanism to retract the pen nib completely, then unscrew the pen barrel.

2. Remove: Pull out the depleted or empty ink cartridge from the internal housing.

3. Install: Insert the new black cartridge with the nib side facing upward into the internal frame until you hear or feel it firmly click into place. Reassemble the pen barrel.

4. Prime: Once reassembled, gently flick the barrel a few times to speed up the ink flow. Click the top to extend the nib and keep the pen pointing downward for roughly 3 minutes to guarantee a consistent, smooth ink flow before you begin writing.
