I love this pen
I love these pens. I started using them years ago. They last for a long time. Very light and easy to hold. I'm not a heavy writer, so this pen's ink flow is great. I don't have splotches on my paperwork. I would recommend them to anyone looking for a nice, light weight, comfortable pen.

Raw
Best pens I’ve ever used. These are actually the ink pens I use because I love the raw feel they provide.

Great value, exceptional quality, beautiful color
These pens write very smoothly. I generally tend to use a Fountain Pen when I'm writing at home or at the office, but these are excellent pens for on the go, as they don't strain the wrist too much. I like the blue color of this ink. It's a pretty healthy, royal blue color, and the pen itself writes a beautiful, thin line. I've been using these pens since they were the ones my first employer always bought, and I've been stuck with them ever since. The price on Amazon was actually less than that I usually pay at my local office supply store!

Excellent writer; a bit short-lived
I write miles every day and have used many hundreds of this particular pen over the years. It is smooth, leaves a nice line, never leaks, starts consistently, and is a nice shade of blue (some "blue" pens are more like "blurple".) The ink doesn't smudge on plain paper, but takes a while to dry on coated paper, much like most other pens. Don't store these with the cap off or it'll dry out. I'd give 5 Stars if the ink lasted longer; I can drain one of these in about 5 days. The law firm for which I work buys the .7 tipped version of this pen by the truckload, but I prefer the .5 tipped Micro so I've taken to ordering them here.

BEST PEN EVER, never leave home without one.
I love these pens, the pen quality is great, the ink is great for signing store receipts, where there what seems to be wax paper, I buy these pens by the box, because of the feel, the grip, ease of use, I keep one with me all the time, never leave home without one, great durability.

Writes smoothly
The I’ll flows nicely, it’s comfortable to hold, and it’s fade proof.
