    • These pens are AMAZING- INCREDIBLE
Size: 20 Count (Pack of 1) Pattern: Gel Pen
I have always had a thing for stationary notebooks pens markers you name it and I've always been on the lookout for the perfect pen and then I discovered these! I have even told friends and family about these pens I've even given them these pens with a couple refills because I knew that once they try these pens they would be sold on them and I was absolutely right. My cousin he writes with his left hand and he always complains how the ink always gets smudged it's just not a smooth writer-until I let him use one of these pens!! He has even claimed that they help him write better as well! A girlfriend in Florida I told her all about these pens- now she AND her husband are hooked on these as well! All the different colors, the different size tips from very fine to bold and everywhere in between. And instead of having to buy pens over and over again you can buy boxes of the refills how convenient is that and cost-effective as well! These are amazing you will not be sorry you will be hooked too and trust me I do a lot of writing a lot of writing I'm one of those creative types and I have to use my own pens these pens and only these pens! And I love all the different colors and it's not just one different kind of blue there's not just one color green there's not just one color pink it's insane the amount of color they have and they all write incredibly well amazing yes they are that awesome no and I'm not exaggerating ... show more

    • Smooth writing
Size: 20 Count (Pack of 1) Pattern: Gel Pen
I love, love, LOVE these pens! Very smooth writing. I include personal messages in my greeting cards and like to match the color of the card ink and can always do it with this set.

    • Bold, Opaque Colors
Size: 20 Count (Pack of 1) Pattern: Gel Pen
Bright colors, smooth line. These feel better than the Pilot G-2s (a tad smoother), and the grip fits my long, thin fingers better. (Those both brands are great.) As other reviews mentioned, the ink doesn't last all that long, but that's true with any gel pen. Store them upright so they don't leak!

I have ordered these pens multiple times. I love the smooth writing (no ugly ink blobs) and the wide variety of ink colors. They are always dependable, except when someone swipes them! ;) Highly recommend!

    • Best gel pen EVER!!!
Size: 20 Count (Pack of 1) Pattern: Gel Pen
Amazing pen quality. Doesn’t smudge. All the colors are vibrant. Once you get ahold of these pens, you won’t go back to regular pens!

    • Love these pens!
Size: 20 Count (Pack of 1) Pattern: Gel Pen
These pens have some of the best ink I've ever used in colored pens. I used them to teach math and color code process and visual relationships in notes. Before I found these, the side of my hand and wrist would have colored speechless and dots from sliding over drawings. This ink writes smoothly, does quickly, and the colors are great. Even the yellow will show up on my document camera and projector! I've gotten colleges hooked! Pentel now gives some color options in the fine and needle tip as well! The barrel size may be a drawback if you like a thin pen, but after some transition time, I've found that I have less trouble with hand fatigue from writing 5-6 hours a day. I keep extras of the standard color pack sand my high school students, ask to borrow them and are color coding their notes as well! ... show more
