Varsity Disposable Fountain Pens (7). Nice on heavier paper but bleeds through terribly on Filofax and 60 lb and lower weights. Review with paper samples.
I picked these up from Oozak.com

I have had these for over 15 years, used them to correct homework (taught English as a Second Language) but apparently have forgotten about them in the back of my desk drawer. Time to use these up. Really like the 0.3 mm tip. Great for smaller spaces. I tend to compensate to the free space I have to write. Give me an entire page and I'll use broad strokes vs. gum wrapper would yield tiny print.
