Purchased at Chrome Hearts Osaka. I bought several items, so the invoice is combined. I will include a copy. Please understand that personal information will be blacked out. The size is the largest men's size, XL. I bought it on impulse because I thought it would be hard to get, but I ended up only trying it on in front of the mirror at home. It's in excellent condition, but please refrain from purchasing if you are overly sensitive. Of course, it's authentic as it was purchased from an authorized store. Due to the authenticity and to prevent swapping, returns are not accepted. I haven't had a chance to use it, so I'm selling it at a low price in hopes of getting some money back. - Material: Silver 925 - Engraving: 925 - Design: Chrome Hearts - Accessories: Pouch Thank you for viewing.
