Refill for EnerGel pens

This roller-ball refill fits Pentel EnerGel retractable pens and delivers blue gel ink through a 0.7 mm conical tip. The liquid-gel formula dries quickly and resists smearing, making it suitable for left-handed writers. Acid-free, archival-safe ink helps preserve signatures and documents. Each refill extends the life of a compatible pen body.

Writers who need quick-drying blue gel ink

Ideal for anyone who wants a smooth, non-smearing line in a standard medium point. Not suited for users who prefer finer or broader tip sizes, or who need refill formats for other pen brands. Buyers who want more storage or different ink colours should look elsewhere.

0.7 mm conical tip size

The tip diameter determines line width and writing feel, so it is the single specification that confirms compatibility with the intended pen and task. Match this measurement to the pen model before ordering.
