Purchased from an authorized retailer about three years ago. I didn't intend to sell it, so I don't have the purchase certificate or shopping bag. m(._.)m The black color with gold studs gives it a luxurious feel, making it versatile and suitable for any outfit or occasion. It's a great item! The shoulder strap length is adjustable. There is some wear and tear, but no noticeable stains or marks. Material: 《Outer》100% Calf Leather 《Lining》100% Calf Leather Please ask if you have any questions. This item has been owned by someone else, so please consider this before purchasing. Thank you for your understanding.
