I've been using a fountain pen since my father bought me a Schaeffer when I started high school - so that's .... 25 years ago! Since then I've been through a few.
My most recent acquisition is a MontBlanc Starwalker medium nib - beautiful pen. One thing that's different and new (for me) about this one is the ink cartridge idea - never had one like this before. Keeps my fingers ink free though.
