This hardware came off of an Authentic Gucci Eclipse Bag that had seen better days. Gucci canvas won’t last forever so make sure you take that seriously when it comes to this material. The threads just become weak over time and there ya go! The eclipse hardware is 1.5 in diameter. Pictures here on a 20inch chain. This chain is around 3/4 of an inch think. Stainless. Both are make of stainless steel so it will not tarnish or rust! When you order, you are only buying the Gucci hardware. The chain of your choice (get with me on the order page) comes free with purchase! ❤️
