Does anyone else remember using these and only these in school?
Pre-ballpoint era, these vintage cartridge pens were the best.
I have three of them, all over 45 years old and all still work as beautifully as the first day they were purchased!
Standard ink cartridges sold by Sheaffer fit these pens perfectly and I use mine daily. Makes writing anything feel like a creative endeavor.
When Sheaffer gave a lifetime guarantee on these pens they weren't pulling the wool over the consumers eyes and I can attest to not only their quality but to the absolute truth of their Vintage marketing.
