I have been looking to buy a monogram strap for my Favorite MM for a while but it's never available. I found on Fashionphile that a few Pochette Metis monogram straps have been listed. While I'm looking to purchase one of those, I can't help but wonder how or why those are coming available. Why would someone sell their Pochette Metis strap? Does anyone have an idea why people are selling them?
