The Bullet (I keep shortening the name because it's so long to begin with) is incredibly simple in style. It's sleek, slim, and unique. I love the way the cap lines up flush with the body of the pen no matter which end it's clipped to. Capped or posted, it's still very sleek and slim.
I don't know what material the body is made of – some type of metal – but there's a clear coat on top of the metal that gives the entire body a nice shine and 3-dimensional look. It's really nice to look at, which is surprising for such a simple design. It just works really well.
All of the parts feel like they're made of high-quality materials. The tolerances in the threads and the cap are tight and feel great. Either I got a really great example, or there is a lot of care put into the quality control on these pens.
One thing I do miss on this pen is a clip. It rolls around very freely on a desk, and I've lost it several times for that reason. An optional clip (similar to Kaweco or Fisher's Bullet pen) would be a great accessory for this pen as long as it was equally stylish and sleek.
