My listings are only on Mercari. Thank you for viewing. This is a platinum vintage fountain pen. It's an ink-stopper type, which was the mainstream style until the 1940s. I found this wrapped in paper while cleaning out the storage room at my parents' house. The original seals are still attached, and they read "Platinum ¥1,500" and "Superior 14K Gold Pen, Japanese Industrial Standards Platinum." It has a retro atmosphere. Although it's a very old pen body, it's an unused item that has been kept untouched. It's in miraculous condition for this type of fountain pen, with no scratches or ink stains. The specific manufacturing year is unknown. After researching, I found a similar fountain pen with "Platinum trade mark 30 year" engraved on the body, dating back to the Showa 20s (1945-1954), but this product has "special K14 pen" engraved under the trademark. I couldn't find the exact same model online, but based on the "RK14 (14K gold filled)" and elaborate design of the cap, the 14K nib, and the "Superior" marking on the seal, it's likely a higher-end model. It's probably a piece with historical value from around the wartime and postwar period. For antique lovers. I think a vintage ink-stopper fountain pen in such good condition, including the seals, rarely comes up for sale, so I've set the price a bit high, but I'm sure those looking for a beautiful item will be satisfied. Please consider this opportunity. I will carefully pack and ship it via Rakuraku Mercari or Yuuyu Mercari. If you are not satisfied with the product after arrival, I will accept returns including shipping costs. Thank you.
