Review: Bought this because I had used it at a business and fell in love with its writing smoothness! - The Pentel EnerGel Deluxe RTX is a fantastic everyday pen. The 0.7mm tip writes smoothly with a nice, consistent flow, and the blue ink is bold without being too heavy. I especially like how quickly the ink dries, which helps prevent smudging. The retractable design is convenient, and the metal tip gives the pen a sturdy, quality feel. It’s comfortable to hold and works great for everything from taking notes to writing lists. Definitely a pen I’ll keep on hand and buy again!
Review: These Pens Are Hard To Beat - I’ve tried every kind of pen over the years—from basic BICs to more “premium” models—but the Pentel EnerGel instantly became my favorite. It writes incredibly smoothly, never skips, and the ink dries almost instantly (except on glossy or coated paper). One thing that really stands out: the ink never dries out, even if you leave the tip out. There’s no need to retract it. You can leave it ready to write, forget about it for months, pick it up again, and it writes immediately. No dryness, no scratching, nothing—unlike BIC and many other pens. It comes in tons of colors, and I use several: blue, black, red, pink, green, and purple, in both 0.5 mm and 0.7 mm tips. Refills come in boxes of 10, and they last a long time. With normal office use, I replace my blue refill (the one I use the most) about every two months. I like these pens so much that I basically retired my old Parker 51—the one I used through high school and college. Compared to the EnerGel, it now feels almost prehistoric. Great performance, great durability, great price. Hard to beat.

### ⭐⭐⭐⭐⭐ Good pens, easy writing with the .7 tips. Smooth ink.
*by M***L on July 12, 2026*

We like these Pentel gel pens. The .7 tips are easy to write with. The red ink stands out and seems to last years on the paper. They write a nice bold line. Love the retractable, so the tips don't get dirty and the pens don't write on things when layed down or moved around. Good pens!
