How to use

Turn the ICO writing instrument to access the refill chamber or remove the pen barrel according to the pen's design. Insert the ICO 0.8 mm Blue cartridge firmly into the feed until it seats securely; ensure the tip is oriented correctly and seated against the pen mechanism. Reassemble the pen and test the ink flow on scrap paper by writing several strokes. If initial flow is slow, allow a few seconds or gently prime the tip by drawing short lines until the ink runs smoothly.
