This is a Pilot "Cocoon" fountain pen (fine nib, F), a popular model. A converter (likely CON-40) is included, but no operational check or cleaning has been performed before listing. After purchase, the included cartridge ink was not used, and a separate converter was attached for use, but the detailed usage situation is vague. It has been stored without maintenance since then. It appears to have been used only for test writing. No noticeable scratches are visible to the naked eye, but macro photos are also included for your reference. Please check the detailed condition in the photos. 【Shipping Method】 It will be shipped via Yu-Packet Post Mini with simple packaging and delivered by post. 【Regarding Purchase】 ・From the perspective of fairness, we do not respond to comments or negotiations aimed at price reduction. (We will adjust the price if it doesn't sell, so please consider it then) ・Please consider only if you understand that this is a used item. ・Returns and exchanges are not accepted to prevent product substitution. ・We may change between Yu-Yu Mercari Bin and Raku-Raku Mercari Bin depending on the situation.
