I don't know the details, but the item is good. It's not cheap. I feel like the thread on the buttons is a little weak. I think it's better to reattach them. The size is M, but it's a foreign size, so it's probably a L or one size larger. The sleeves are long, so I was wearing them folded up. That looks cool! I'm selling it to organize my clothes. I've taken good care of it with leather cream, etc. It has a great feel. Thank you.
