Looks
Not to be superficial, but I kind of think other pens are jealous of how hot this pen is. I know that's just personal preference, but I'm smitten.
The Lamy 2000 is unique. There isn't another pen like it in design. It's sleek, modern, and welcoming at the same time. It looks like a pen meant to write, but classy at the same time. It works with casual and dress clothes splendidly. It always gets comments out in the wild.
One of my favorite aspects of the pen is the grip and nib section. The nib is hooded, and looks very small since most of it is hidden beneath the metal grip. Now, I'm no expert in metals, but I think the grip is stainless steel. Whatever it is, it feels fantastic to hold.
The body is made of Makrolon, a form of fiberglass. It looks unique, but it also feels unique. It's a subtle difference, but I always notice it. After you write for a while, the body warms up as it rests on your hand. When writing, my fingers rest on the stainless steel grip and the body rests on my hand. I've written with this pen over numerous long writing sessions, and it never got uncomfortable. It's a great material, and well-balanced in the hand.
I normally write with this pen unposted, but it also feels well-balanced when posted.
The pen is a piston filler, and the piston section is so flush with the rest of the pen body, that it's often easy to miss. I love this aspect of the design. It makes the pen look like a solid, single piece.
Another fascinating design feature is the ink window. Toward the grip section of the barrel, some of the Makrolon is thin enough to let light through so you can see (roughly) how much ink is left. This is nothing similar to a demonstrator body – it's in no way completely transparent, but it does allow you to keep an eye on your ink level. It's a great feature.
