Federico Buccellati silver fountain pen. This item is from my father's study. The case shows signs of aging, and there is some silver-specific deterioration, but the pen is unused. Please check the photos for the condition and included accessories. The nib is 18k 750 gold, and the cap also has a serial number engraved on it. Currently, it is not found in domestic auctions, so I believe it has a high rarity value. I would be happy if it could be passed on to a collector. Feel free to negotiate the price! There are blue stains on the silver inside the case. I believe this is due to aging and storage of the metal. This is an unused, pre-owned item, so please refrain from purchasing if you are looking for perfection.
