How to use

Disassemble the compatible Diplomat pen according to the pen model's normal procedure, remove the empty or worn refill, and insert the new Diplomat refill into the barrel until it seats securely. Reassemble the pen and test the flow on scrap paper to confirm consistent ink delivery before regular use. If the pen has a retractable mechanism or metal tip sleeve, ensure these components align and operate smoothly after installation.

Usage recommendations

Store spare refills in a cool, dry place away from direct sunlight. For best results, use on standard office paper and avoid prolonged storage with the tip facing downward to reduce the risk of leakage. If skipping occurs initially, scribble briefly on scrap paper to condition the ink flow.
