This is a men's formal accessory set that I kept as a memento of my father. Inside the box, there is a plate that says "Quality Guarantee" and "High-Grade Product," but the details such as the material and type of stone are unknown. I do not have specialized knowledge, so I cannot provide accurate information. Due to long-term storage, there is a general feeling of use, verdigris, and aging. The condition is not very good, so please purchase only if you understand that this is a junk item, a collector's item, or a material for remaking. 【Notes】 ・Please purchase after agreeing to the condition. ・No claims or returns (NC/NR) are accepted. ・Immediate purchase is welcome.
