20-Pack Ballpoint Refills

Each package contains 20 black ballpoint ink refills with a 0.7 mm medium tip, supplied new for immediate use. The set is intended for writers, students and office workers who want a ready reserve of cartridges for everyday note-taking and document work.

0.7 mm Medium Tip

The single specification that determines fit is the 0.7 mm medium ballpoint tip, which produces a standard line width compatible with many retractable pens. Buyers whose pens require a fine or broad tip, or a rollerball or gel refill, will find these cartridges unsuitable.

Consistent Ink Flow

Under sustained writing sessions the refills maintain a steady ink delivery without skipping or blotting, supporting extended journaling or meeting notes. The plastic barrel holds 0.02 kg of ink per unit, and the cartridges can be trimmed to length for use in shorter pen bodies.

Questions about this item

What does the 0.7 mm tip width mean for everyday handwriting?

The medium 0.7 mm tip produces a standard line weight suited to note-taking, journaling and general office work, giving a consistent ink flow without feathering on typical paper.

Which pen standard do these refills follow, and what does that limit?

They follow the common ballpoint refill form factor used in many retractable pens, so they fit only pens designed for that standard and will not work with rollerball or fountain pen bodies.

Can the refill be trimmed to fit shorter pen barrels?

Yes, each refill can be cut to length with a sharp blade, allowing you to match the exact barrel depth of your preferred pen.
