The hardware is aged gold so it’s already got a discoloured appearance but definitely on my lighter coloured 25 bags I’ve noticed wear on the leather interwoven into the chain from rubbing. Both black marks from the aged gold hardware and actual small frays to the actual leather from the cc clasp when the leather is being pulled through. Neither are noticeable unless you look very closely but it’s definitely a hazard of wearing the bag. I personally think this bag is one to be used and enjoyed - it’s a daily bag - so im not very bothered. If it was an occasional special bag I would be more bothered about it.
