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.
