- Dries quickly, reducing smudging—great for right- and some left-handed users

## Cons

- Plastic body, though sturdy, may feel less premium than metal pens (but still durable)

The Pentel EnerGel RTX 0.7mm is a top-notch gel pen that combines smooth ink flow, quick-drying ink, and a reliable design—great for anyone who writes a lot and appreciates a neat, professional look.
