Gel refill for ballpoint pen PILOT G1, green ink, model G1 (RBLS-G1G)

Gel refill for ballpoint pen PILOT G1, green ink, model G1 (RBLS-G1G) is a replacement gel cartridge designed for G1-style pens. The refill provides smooth gel-based ink flow in a clear green color suitable for everyday writing tasks, note-taking and document marking. It fits into compatible retractable and capped pens that accept G1-type cartridges and is intended to restore or extend the life of an existing PILOT G1 pen or other pens built to the same refill standard.

Advantages

This green gel refill delivers consistent, skip-free writing with a fluid gel formula that reduces drag on paper. The ink dries relatively quickly compared to heavier gel formulations, helping to minimize smudging on common paper types. The cartridge is sized to match G1-style refills, enabling straightforward replacement without tools or modifications, and provides reliable color contrast for annotations and color-coding.

Suitable for

• Everyday handwriting and note-taking
• Office forms, documents and annotations requiring green ink
• Color-coding, corrections and highlighting in planners or notebooks
• Replacing empty cartridges in G1-compatible pens

Key specifications

• Ink type: gel-based ink in green
• Tip style: ballpoint/roller compatible with G1-style cartridges
• Compatibility: fits pens that accept G1 refills
• Intended use: writing, note-taking, document annotation

How to use

To replace a spent cartridge, remove the old refill from the pen according to the pen’s manufacturer instructions, then insert the G1 gel refill until it seats securely. Ensure the tip is exposed and test on scrap paper to confirm smooth ink flow and correct alignment. Store spare refills capped or in their original packaging at room temperature and avoid prolonged exposure to direct sunlight to preserve ink quality.

Usage recommendations

Use on standard office papers, notebooks and planners. Allow a moment for ink to dry before stacking or closing pages. If leaving a pen unused for extended periods, retract or cap the tip to prevent drying. Replace with an identical G1-style refill to maintain optimal fit and writing performance.
