These new ink cages act like an ink reservoir for a pointed pen nib, allowing for lines and lines of writing without re-dipping! Each ink cage comes permanently attached to the specific nib, they are not removable or reusable.
Detailed information about the performance of this nib can be found here.
For water-based ink, clean the nib by dipping it several times in a small jar of tap water.
Add a small amount of pen cleaner to the water for cleaning heavier pigmented inks.
Then, pat dry on a folded piece of paper towel rolling it side to side on both sides, being careful on the cage side.
Repeat if needed.
A little ink residue or staining in the cage area will not affect the nibs performance.
For best performance clean between every other dip depending on the ink build-up.
Do not scrub the Ink Cage or keep the nibs soaked in cleaning solution or use hot water to clean.
Ultrasonic cleaners are also not recommended.
