You don't see this very often. This was close to where I live - the NOS stock of an old pharmacy went up for auction from the estate of the pharmacist. There were tons of pharmaceutical things, razor blades, and a lot of what you could buy in a drug store probably 50 years ago.
I got these....I will be able to offer my customers all sorts of fun pens for at least a year. Yes, I will keep a few for myself.
