My listings are only on Mercari. This is a dedicated listing. I apologize, but please refrain from purchasing if you are not the intended buyer. Thank you for viewing. This is the old-type nib from Platinum's masterpiece "＃3776" series. It's a 14K nib with a fine (細字) width, indicated in kanji, and has the JIS mark. There is some stubborn dirt on the back of the nib that doesn't come off easily even when washed. I didn't force the cleaning for fear of deformation, and since it didn't affect writing, I left it as is. The front side, being the face of the fountain pen, has been cleaned thoroughly. This item was originally attached to a Gathered fountain pen that I owned. During the year-end cleaning, the fountain pen rolled under the furniture. I didn't notice and placed the furniture on top, resulting in an unpleasant "crackling" sound. When I moved the furniture, I found the Gathered pen was broken. This was the last tragedy of the year (probably)... Fortunately, the damage was to the barrel, and the nib was not affected, so the nib remained intact. As shown in the images, the nib is large for a fountain pen, and weighs between 0.6 and 0.7g. Currently, the market price for 1 gram of 14K gold is over 14,000 yen, making it a valuable asset. However, I want to utilize it as a nib as long as it functions, so I'm offering it to someone who needs it. As those who have handled the ＃3776 series may know, this series is characterized by its firm and solid writing feel. The fact that the series name is the same as the altitude of Mount Fuji is very similar to a certain series from a certain manufacturer, and you can feel Platinum's strong enthusiasm at the time, "We want to make the best, top-of-the-line fountain pen." The technology and passion of that time are embodied in this nib. If you have a Gathered or old-type Century with a nib problem, I hope you will consider this as a spare. I will ship it via Rakuraku Mercari or Yu-Yu Mercari with careful packaging. If you are not satisfied with the product after arrival, I will accept returns, including shipping costs. Thank you for your consideration.
