    • I love this pen.!!!
Color: USA Barrel / Black
This is my favorite pen. I’ve bought it multiple times and I love it. I share them with co-workers all the time. Writes smooth, represents America and just works. They are well made and I even found. 1.0 black ink replacement, it is super smooth.

    • Best pens ever!!
Color: Burgundy
Buy these pens! You will never find a better, smoother writing ink pen! I write a TON at work- all day- so I have tried a lot of different brands and hands down the pentel energel are absolutely the best! They are priced just right too! Long lasting, doesn’t smear, and come in many vibrant colors.

    • Best gel pens ever - smooth, vibrant, never skips!
Color: Black
The Pentel EnerGel RTX is my absolute favorite pen! The 0.7mm gel ink flows beautifully with zero skipping or smearing. The retractable design is convenient and the metal tip feels smooth. Black ink is rich and vibrant on any paper. I've bought these for years and they never disappoint. Best gel pens available! ... show more

    • Best Blue Pens!
Color: Blue
I’ve always been picky on pens and pencils and Pentel quality does not disappoint. I tried the energel RTX blue 0.7 ink first in a different multi-color set. I usually prefer unique colors (absolutely LOVE the navy-blue and turquoise energels) but something about this regular, “boring” blue color struck me. It was vibrant without being too bright and the perfect shade. I like signing documents in blue (old habit from legal work days) so bought a whole pack of 12. As all pentel energels, ink flow is super smooth and I love how the pen feels on paper. They may not be the cheapest pens out there but quality makes it definitely worth it. These will probably last me a while!! ... show more

    • Perfect, just what I needed
Color: Black
I do a significant amount of calculations and note-taking at work, so having a dependable pen is a must. These pens have been excellent so far and have not disappointed. The ink flows incredibly smoothly, with no skipping, smearing, or interruptions while writing. The writing experience feels effortless and consistent, even during long periods of use. I personally prefer gel pens over ballpoint pens, and these deliver exactly the smooth, clean performance I look for. If you're someone who writes frequently and values reliability and comfort, these pens are definitely worth considering. ... show more

    • Great quality vs G2
Color: Black
I bought these pens to try to find an alternative to the pilot G2. After writing with them for a little bit I noticed my hand started hurting a bit, the grip is a little bit larger than a G2. I love the ink and how they write just wish they were more comfortable. I ended up taking the ink from the Pentel and putting it in the Pilot G2 body and I think that’s the perfect combination! ... show more

    • My favorite all-around gel pens
Color: Blue
My favorite all-around gel pens. Decent value. Intelligently designed. Nice grip and writes on difficult surfaces. I prefer the medium (0.7mm) size metal tip (from experience). My go-to pen for signing my signature.
