(1) Dozen Box of - Series 860 Paper Mate Metal Clip Fine Line Marker Pen - Blue Ink, Model 861-11. Vintage 1980s. Found in shipping boxes full of office supplies from the 1980s never opened. I opened the box to test a few of the pens and they are still working like normal. There is a fine film on the pens I assume is from the aging of materials in the box. It wipes right off revealing a new looking pen. These are no longer in production. Made in USA.
