I found a 3-pack of these .7mm pens in a Target store a while ago, and I picked them up without ever having heard of them. They're a sort of hybrid ink that is supposed to have the darkness of a gel ink with the drying speed of a ballpoint. I think they deliver on that promise pretty well.
The "Pure White" label just refers to the color scheme, as far as I know. As you can see in the pictures above, the pen is white with a silver band at the top and a slightly rubbery silver grip.
The lighting I used here is the same as the other two above. It's a "full spectrum" fluorescent light, but it does sometimes give me a yellowish tint. That's why my ink pictures are coming a little slowly. It's been overcast for quite a while here, and I haven't had much natural light to work with. What do y'all use for pictures?
The knock on this pen is stiff and springy. It's got a soft click that I quite like, and the knock doesn't rattle when you write with it. Good form, Pilot.
Here's the tear-down photo. This pen does come apart more than most other similar pens.
One thing about this pen is that the line is much more fine than I was expecting. I've compared it to a bunch of other pens that I had sitting around. Most of these are hybrid rollers of one type or another.
The tip size is pretty similar to the EnerGel pens (first and third of the left of the Acroball counting anticlockwise), but they're both .5mm tips.
The ".7mm" of the Acroball is nowhere near the .7mm of these other pens. It's actually a bit thinner than the .5mm pens, but I think that's a matter of the ink itself. The EnerGels and such have more a gel character than the Acroball, so they have a bit of spread, and that makes them seem wider than they would otherwise be.
I'm a fan of this pen, but only when I want to write very small. It makes my hand look too spidery when I use my normal handwriting with this pen. If you've got a small handwriting style, then this is going to fit the bill for you. They can be found in lots of places,
including Jetpens.com, in lots of colors and styles.
