At age 20 I was intrigued by a red Sheaffer No-Nonsense, which I bought with some cartridges at a local small office supply store. I've since moved on to much better pens, but that was my first.
A Schaefer cartridge pen. Probably around 1963.What Was Your First Fountain Pen & How Old Were You When You Got It?
I was in third grade (8 years old in 1965) when I bought my first fountain pen. Our grade school had a vending machine that had various writing implements. Among these was a very cheap fountain pen. It had a cardboard feed and wasn’t refillable, but they were cheap.
My first significant fountain pen was a black Sheaffer that I got for my birthday in junior high school (7th grade).
