Hi everyone! I finally joined the Herbag club after purchasing two of these amazing Hermes handbags on eBay. The first one I bought is the mm size which came with a shoulder strap, and the second is the pm ado backpack. When the smaller size arrived I was a bit disappointed to discover that the shoulder strap I had isn’t compatible and doesn’t fit in the slots alongside the carrying handle. The leather at the upper part of the bag is very stiff and I don’t want to ruin it by trying force the two of the straps in together. Has anyone else have encountered this problem? Is the ado model isn’t designed to fit a shoulder strap because it’s supposed to be a backpack? Thank you all in advance!!
