Ballpoint pen refill PILOT BLS-G1-5-L — black ink, transparent barrel, compatible with G105

PILOT BLS-G1-5-L is a replacement ballpoint pen refill designed for everyday writing tasks. The refill contains black ink and is housed in a transparent barrel that lets you check remaining ink visually. It is compatible with pen bodies that accept G1-style refills and is noted as suitable for use with the Pilot G105 gel rollerball.

Advantages

The refill delivers consistent black ink flow and a reliable writing line for note-taking, form filling and daily office use. Its transparent barrel enables quick visual inspection of ink level while the standard G1-sized tip and dimensions make it easy to replace in many compatible pens. Using a refill reduces waste compared to discarding an entire pen.

How to use
