How to use

To replace a cartridge, unscrew or remove the pen barrel according to the pen model instructions, withdraw the empty cartridge, and insert a new sealed cartridge firmly into the feed until it seats. Reassemble the pen and allow a few moments for the ink to reach the nib; if necessary, gently depress the cartridge or prime the nib by lightly touching it to scrap paper. Store unused cartridges in their original packaging at room temperature away from direct sunlight.

Recommendations

For consistent performance, use these refills with fountain pens specified by the manufacturer. Avoid exposing cartridges to extreme temperatures and do not puncture or refill cartridges manually. If ink flow is slow after installation, try a few light strokes on scrap paper to encourage ink flow.
