Purchased in Italy during a trip. It has a stylish design, and I was often asked "Where did you get that jacket?" when I wore it. Although not visible when worn, I had the initials AK put on it at the store where I bought it as a memento. There are brown stains on the inner tag (see photo 7), possibly due to aging. I had it professionally cleaned and stored. There is some pilling on the ribbed cuffs (I thought it could be removed with a fabric shaver, but I didn't mind it, see photo 8), and a brownish appearance on the inside of the sleeves (see photos 9 and 10), indicating some wear, but I think it can still be worn. I would be happy if someone who likes it despite these imperfections would like to have it. The leather has a nice feel, and the long ribbed sleeves are stylish whether the front zipper is closed or open.

I researched it, but couldn't find a definitive answer. I believe it is genuine leather, either calfskin or cowhide, and a quality guarantee. I apologize for not knowing the exact details; if you are concerned, please refrain from purchasing. From the website ↓ 《VERA PELLE/Vera Pelle》Quality guarantee of the Italian Vegetable Tanned Leather Consortium. Vegetable tannin extracts used in a natural process that takes time without using chemical compounds enhance the scent and quality of the leather, maintaining its unique softness, warmth, and durability over time, and preserving the original characteristics of the leather. For centuries, Tuscan artisans between Pisa and Florence have been incorporating technological innovations while maintaining this valuable traditional craftsmanship, which is the hallmark of VERA PELLE. ↑ There are no other areas of particular concern, but it has been carefully stored and is a used item stored at home.
