I have had the pallas clutch for about 2 years, have worn it a fair amount of times since then but it has not been an every day bag and I take good care of it. There is a fair amount of chipping of the brass zipper pull, which I started to notice about 6 months after I got it. The brass clasps on each end of the removable strap are still flawless, it is just the zipper that is chipping. Should I take my bag into the LV store to get a new zipper pull, or is this chipping normal and expected? Thanks for any insight!
