Sheaffer 300
I've been using my Sheaffer 300 medium nib now for a couple of months and really starting to love it. When i first started using it with the proprietary cartridges I was a little disappointed. It seemed to be a rather dry and scratchy writer; however, now that I am using the converter and filling it with Diamine Oxford Blue I find it very satisfying. Amazing how much better this pen feeds with bottle ink rather than cartridges.
