Everyday refill pack

The DUNBONG DB-N1BX-3C delivers five black ballpoint refills in a 1.0 mm medium point. Metal bodies keep each cartridge light and durable for daily writing. The pack suits office workers, students or anyone who goes through ink quickly.

Metal construction and fit

Each refill measures 3.9 inches long by 0.24 inches wide with a metal barrel that resists bending. The standard dimensions match many popular pens, though buyers should compare the original refill before purchasing. Five units provide enough supply for extended use or sharing.

Consistent flow and quick drying

Ink lays down smoothly without skipping and dries fast to prevent smears on the page. The medium point balances line width and control for notes, forms or correspondence. No special maintenance is required beyond normal pen care.

Questions about this item

What is the 1.0 mm medium point size designed for?

The 1.0 mm medium point delivers smooth writing with quick-drying ink that will not bleed through paper.

What are the exact dimensions of each refill so I can check compatibility?

Each refill measures 3.9 inches long by 0.24 inches wide and high, weighing 14 grams with a metal body.

How do I install these refills correctly and what is the common mistake?

Unscrew the pen barrel, remove the old refill, insert the new metal refill, and reassemble; the common mistake is not verifying the 3.9 inch length and 0.24 inch diameter match the original refill before purchasing.
