This is a key hook that combines a unique hook type with a shackle. All materials are solid brass, and you can enjoy the aging process the more you use it. By the way, the total cost was about 3500 yen. I remember the hook itself was expensive. Below are the dimensions of each part. These are amateur measurements, but I hope they are helpful. Total length: 11.5cm Hook body: 7.5cm Shackle: 2cm Double ring: 3cm That's all. All parts combined are unused, but there are some minor issues. About 4 years ago, I was looking for a key chain or key hook that I liked, and this was one of the things I tried. I combined all the parts I purchased myself, and I was looking for a solid brass hook with a shape like the Red Moon silver hook, and I remember that I really couldn't find the design of the hook body. It seems to be from a brand, and it had the brand's engraving. I'll upload a close-up image. In the end, I'm selling it because I'm still using another item I bought at the same time. When assembling it, I didn't need any tools, just opening and closing the shackle, but when I saw the finished product, I realized, "This hook body isn't straight." I'm not sure if it has a curve to fit the body, or if it's just a defective product, but I wanted to straighten it somehow, and as a result of struggling to bend it with a bench, the body became straighter than before, but the bench marks remained. There are a few small scratches that are noticeable up close, and there are some areas that catch when you run your finger over the surface. Therefore, it is in a state of "unused but with some scratches and dirt," and "the hook body is curved + there are some small scratches from the pliers." It may not be suitable for those who are sensitive, but I think it won't be a problem for those who don't mind and use it. Please consider that point when considering purchasing. I plan to list other key hooks as well. Please take a look at my listings if you'd like. Thank you.
