Compatible refill for EnerGel RTX

This refill fits Pentel EnerGel RTX and EnerGel Deluxe retractable pens. It uses a metal tip to deliver liquid gel ink in black. The ink is acid-free and archival safe for long-term document storage. It dries quickly to reduce smearing during use.

Writers who need a bold line

The bold point produces a wider stroke suited to signatures or emphasis. Users who prefer a finer line for detailed notes or small handwriting should choose a different refill. Left-handed writers benefit from the quick-drying formula that resists smudging on contact.

Ink performance characteristics

The liquid gel ink flows consistently through the metal tip without skipping. Acid-free formulation prevents paper degradation over time. Quick-dry properties keep pages clean during immediate handling. Black colour provides strong contrast on white or light paper.
