This Parker Ad-Pen is in effect one of the series of "Big Red" rollerballs that Parker manufactured in the 1970s that were styled on the 1930s Streamlined Duofolds. This is a new-old-stock Ad-Pen, still in its box and unused. It has no damage at all. Both cap and barrel are glossy and scratch-free. It will accept a standard Parker type rollerball refill - I will include a new refill with the pen as the old one was dry. The cap has a black top button holding on the chrome-plated washer style pocket clip. This has a ball at the bottom and "AD PEN" imprinted down the tapered stem. The flat ended barrel unscrews to allow the changing if the refill. The black finger grip has a very comfortable design with a flared ridge making it very easy to hold. The box is made from red paperboard and has a couple of very minor scuffs on the outside.
An unusual item, very practical too.
