New, old sales sample Garland Twin-O-Matic Pen and Pencil halves.  My father was a sales representative for Garland many years ago, and we came across these stored in a garland box (not included).  They were still wrapped in tissue paper, and appear to be an unused sales sample or business gift set.  It does not include the centerpiece that goes in between each side (which would normally have been engraved or used with a business logo).  The pencil is full of lead, but the eraser looks dry and would be unlikely to work properly (can be replaced).  I tried briefly to write with the pen, 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 (pen insert is also replaceable).

Please feel free to message me if you have any questions.
