Six classic Erasable Ink Pens. All are Dead.

Total of six pens: 4 Scriptos and 2 Eraser Mate (Papermate) all with caps and erasers.  

None write, but all erase (and that's the point, eh?). 

These Black Stick Pens (Circa 1980's) were a godsend-ace-in-the-hole for GEN X test takers and everyone had to have one.  

The result was a terrific PR battle between Scripto and Papermate both of whom had similar technology which involved a thick ink made of plastic.
