This is a GUCCI ball chain, made of silver 925. I have several ball chains, but I thought it was rare that only one of them has the GUCCI engraving on the clasp. Moreover, it seems to have a hallmark. When straightened, it's distorted... it doesn't become straight, but it can be used normally as a ball chain. Please refrain from purchasing if you are concerned about the distortion. m(_ _)m [Brand] GUCCI [Material] Silver 925 [Color] Silver [Length] See image No accessories included. Thank you.
