This is a Calvin Klein accessory that is no longer sold. It has a stylish design with a blue stone set near the cross-shaped indentation, and the material is stainless steel. The "sus" marking is on the third image. Please be aware that there are minor scratches and signs of aging. I apologize, but I don't remember the exact size, but I think it was around size 11 to 13. Please understand that this is not exact. I am also selling other Calvin Klein accessories, so please take a look if you'd like. I will discount 200 yen for each additional item purchased. Thank you.
