This is a dynamic wheel-shaped stamp ink pad distributed by the Japanese National Railways. It's covered in 24K gold plating and shines brilliantly! There's an engraving on the back (photos 6 and 7). It also has a substantial weight. The chrysanthemum crest on the inside of the lid confirms it's from the Japanese National Railways era. This is a very valuable item. Recommended for railway enthusiasts. Ink pad material: Paste ink Size: 50mm diameter, 16mm thickness Weight: Approximately 89g Processing: 24K gold plating ・Made in Japan ・No product case ⭐️There is some overall soiling, but I think the gold plating is well-preserved for its age. There is some soiling on the inside of the lid and the bottom of the main body. ⭐️The paste ink is not dry, but moist, and adheres well, so you can use it for a long time. ⭐️I take great care in storage, but it is a personally stored item, so please check the photos for the condition and make your judgment. ☆Purchase without comment is welcome. If you have any questions, feel free to ask. 【Shipping】 Although it's not the original case, I will send it in another case that is about the same size (photos 12 and 13). Thank you.
