For sale: Cartier pen Most sold pen at Cartier The pen is very clean and the customer can inspect it at one of Cartier's branches. It's rarely used because I have another pen I use for work and this one is kept aside. The price is 1200, and only serious buyers should inquire. Don't offer less than that because I'm not in a hurry to sell it. If I don't get 1200, I'll keep it.
