This is a WATERMAN fountain pen. It appears to be a cartridge type. The nib is stamped with an "F". I don't know the model number or other details. I received it as a gift in 2007, but I have never used it and have kept it at home. I don't think I will have a chance to use it in the future, so I am offering it for sale in the hope that someone else will. Although it is unused, there is a small scratch on the box (see photo). Please consider this item if you understand that it has been stored for a long time.
