I purchased this item approximately four years ago at a GUCCI store in Japan. I have unfortunately lost the storage bag and guarantee card, but it is authentic. Although it's a men's item, I, a woman, was also able to wear it, so I believe it has a unisex design and size. I have used it less than 10 times. This is a GUCCI black cap made of nylon with a mesh back. As shown in the 10th photo, there is a small stain on the front, but since it's black, it's not very noticeable when worn. - Brand: GUCCI - Color: Black - Material: Nylon - Features: Mesh back - Logo: GUCCI logo - Design: GG pattern Thank you for viewing.
