VERY RARE CARTIER GOLD FOUNTAIN PEN. I had this pen for while and hardly ever used it. It is a great collectors piece, all original. Excellent condition, NO DAMAGE AT ALL. Please look at the detail images and as you can see it has been kept with care. Still have the original box in which it is stored in at all times. Most pens on here are either silver or half gold and you can see this is very unique.
