Pack size and intended users

Dimensions, customisation and gifting

Every cartridge measures about 10.7 cm or 4.2 inches long and can be cut to fit shorter pen barrels. The spring‑loaded design makes installation straightforward. The quantity and practicality also make the set a convenient gift for colleagues, friends or family members who use retractable pens.

Questions about this item

How do I install the Sepamoon 1 mm refill into a click retractable pen, and what step is often missed?

Remove the old refill, compare the new 10.7 cm refill to your pen barrel, cut the plastic tube if it is too long, then insert the refill with its spring into the click mechanism.

What part of the Sepamoon 1 mm refill will need replacement first with regular writing?

The black ink supply inside the plastic tube will run out before the 1 mm ball tip wears down; each refill is single-use and cannot be refilled.

What limit appears first when writing continuously with the Sepamoon 1 mm refill?

The 1 mm ball delivers a steady line until the ink depletes; sustained heavy writing will exhaust the ink volume before the tip shows any wear.
