Pentel of America, Ltd. EnerGel Deluxe RTX Pen 0.3mm Black BLN73A

Everyday writing tool

The Pentel EnerGel Deluxe RTX is a retractable liquid-gel pen with a 0.3mm tip that produces crisp, extra-fine lines. Its fast-drying ink prevents smears for both left-handed and right-handed writers. A latex-free Comfort Zone grip improves control and reduces fatigue during long sessions. Sold as a single unit for daily use at home, office or school.

Upgrade from basic ballpoints

This pen replaces standard ballpoints that skip, blob or smear on quick notes. The liquid-gel hybrid ink dries in a flash, so the jump is worth it whenever you need clean, consistent lines without waiting for ink to set. It also eliminates the pressure required by cheaper refills, making extended writing more comfortable.

Suits detail-focused writers

Ideal for students, professionals and anyone who prefers an ultra-fine point for notes, forms or intricate work. The 0.3mm tip excels at small handwriting and tight spaces. Writers who need broader strokes, bolder colour laydown or a refillable metal barrel should look at something else.
