Hello to Marc-Barr, and others looking for refills on the 4-inch Tiffany purse pen. (4 inch! not 4-1/2 or 4-5/8 or 4-3/4...) I don't know when this was made, but the main Tiffany store on Firth Avenue in NYC has moved on, perhaps even several generations forward in their size of purse pens, and they couldn't help me at all
To make matters worse, this pen (found in my parents stuff) has lost its 'spring' or whatever the mechanism is called that keeps the cartridge in place.
I wondered whether Marc-Barr you had found any solution to your problem - of getting a refill?
