I do not use stock photos or photos of other people's items. This is an original must de Cartier fountain pen.
There is ONE CARTIER ink cartridge. It is a "Trinity" 5 microns plaque de or with the three color gold bands on the cap. It has a Godron/ striped barrel. It is serial number 636XXX.
The nib is marked with the CC logo, 18K 750. I do not know the fineness of the nib by sight. I will be happy to answer questions about a particular item to the best of my ability.
I will not be able to issue discounts after the invoice is paid as a result of E-BAY requirements. Please contact me if you have any questions.
