I then examined the pen a little closer and found the name Cardinell Erado-Pen on the side of the barrel. This is the only information found on the pen. I assume that the glass vial held the ink remover/eradicator and that the rubber end allowed the liquid to be blotted onto an inky mistake on paper or cloth?
If anyone has information/history for the Cardinell company or knows anything about this particular product I would be greatful.
I look forward to hearing from the very knowledgeable folks on the Board!
