TWSBI Diamond Mini Classic

I purchased this pen because I wanted a a shorter piston-fill pen with an extra fine nib. In regard to length, the pen satisfies need. While too short to write with comfortably un-posted, the capped pen clips discreetly above the breast pocket with only the clip and finial showing. The steel nib writes smoothly with good ink flow but the nib is hard, so those who prefer a springier nib will be likely be disappointed. Due to its abbreviated length, the ink chamber is smaller than other piston-fillers, such that capacity is similar to a larger converter. But as the barrel is clear, one can see ink level easily. The pen has been less than desired only in one respect -- as another Asian brand, I hoped the extra fine nib was like Japanese extra fines, i.e. REALLY fine, but it is closer to European standards.

TWSBI Diamond Mini

It is well made, with a substantial feel, and a light ink flow. Many nice touches, including a screw-on posting, and a set of maintenance tools,and an o-ring seal for the cap.

upper-end pocket pen

demonstrator pocket pen. shows off the ink. needs to be posted (caution, it can be easy to cross-thread the cap so be careful) so takes a little more time to use. not really intended for long-term writing. a larger nib and ink capacity makes it a step above something like a kaweco sport. a solid 4 star pen but would rank it higher if the price were a bit lower.
