This is a jewelry case from AHKAH. The color is navy (dark blue). It's made of a high-quality velvet-like material. I believe it was about 10 years ago that this jewelry case was sold as a limited edition item from AHKAH. I think the retail price was around 20,000 yen, but I don't remember the exact amount. I only used it a few times and used other jewelry cases, so I've kept it stored at home. It's in overall good condition, but due to long-term storage, the corners of the exterior have a slightly reddish tint. (The photos from the 5th one onwards show the redness more prominently due to the flash, but in reality, the color difference isn't so clear, and it's not very noticeable at a glance. The images from 1-4 are closer to how it looks to the naked eye.) Please confirm the current condition in the photos and purchase only if you are satisfied.
