I have few comments on this pen that differ from those I made upon the X450. The main point of difference is the slightly less traditional shape of the body; the X750 has a more modern sense to it. There is also no suggestion of ergonomics on the section. The one I examined seemed a little more willing to allow posting of the cap than the X450, too, but it is not exactly positive about it. I frankly would not bother with posting, as this puts the pen’s centre of gravity high in the air.
Production Run: Unknown start, in current production.
Cost When New: Low indeed. It’s hard to find one above $4.00 on eBay, and at established online shops, it usually goes for less than $10.00.
