Vintage Garland Silver Twin-O-Matic Pen Half and 46 similar items

Vintage Garland Silver Twin-O-Matic Pen (Half) New, old stock Garland Twin-O-Matic Pen. My father was a sales representative for Garland many years ago, and we came across these stored in a garland box (not included), still in the plastic sleeve. I personally don't know a lot about these pens, but I presume this is the pen side to the other pencil side of the instrument. I also have a few pencil sides that were in the box as well that I can list, though there weren't any other sleeves or items in the box that would have put the two sides together. Note: I took two of these out of their sleeves and tried to write with them, but no ink came out. It's very possible the ink is dry, or that it would take more work to get it to flow. Please feel free to message me if you have any questions.
