I am selling this Montblanc Quick Color SL (Slimline) two-color ballpoint pen from the eighties. It holds a red and blue filling and can switch between them by twisting the pen. Obviously the pen switches and writes well. Montblanc doesn't produce any multi color pens anymore so these pens are uncommon. This pen has been used but still looks good and comes delivered in the original box with booklet that even retains the original cardboard sleeve. This auction will be started without a reserve price, please examine the photos before bidding.
