Pilot G2 1.0 mm Black Refills 12 Pack

These Pilot G2 gel ink refills come in a 12-count pack with a 1.0 mm bold point in black. They are designed for writers who want to keep using their existing refillable Pilot G2 pens instead of buying new barrels. The refills suit everyday note-taking, journaling, and office documentation.

Simple drop-in replacement for compatible Pilot pens

Installation is a straightforward barrel swap: unscrew the grip section, remove the empty refill, and insert the new one until it seats. The main issue is attempting to fit these into non-Pilot models or Pilot series that use a different refill profile, which will not accept the cartridge.

Confirm your pen accepts G2-style refills before

Check that your current pen is a Pilot G2 or another model explicitly listed as compatible with G2 refill cartridges. The 1.0 mm bold tip lays down a wider line than fine or ultra-fine versions, so verify that line width matches your preference. The pack weighs 0.04 kg.

Questions about this item

How can I confirm the 1.0 mm refill writes smoothly after installing it?

The Pilot G2 18538 refill uses quick-drying gel ink that glides across paper and resists smudging, so a few test lines should show clean, consistent flow without skipping.

What comes in the pack and is anything else needed to start writing?

The box contains 12 black 1.0 mm gel ink refills weighing 0.04 kg total; no additional parts are required — simply insert one into a compatible Pilot G2 barrel and write.

Which Pilot G2 refill version matches a bold 1.0 mm tip for everyday notes?

Choose the 18538 model listed as Bold Point 1.0 mm; it is the specific extra-fine/ultra-fine formulation supplied in this 12-count pack for standard G2 pens.
