MI902  Barlow Desk Set Style Ballpoint Pen - Black matte finish with gold electroplated trim, twist to extend Cross style ballpoint refill. Measures 6.75 inches long, diameter is 5/16 inch. This is a nicely finished desk pen that fits many desk sets. Desk set pens seem to go AWOL over the years, I know I’m always looking for replacements! It doesn’t fit ALL desk set pen sockets, but just might be the answer to your empty pen socket while you search for the correct pen. New condition. (several avail)
