I have the Monceau and it is a lovely bag. From your list I have experience with Deadly Ponies. I have had three of them, the Mr Fill n Zip, the Mr. Mini Armadillo and currently I have the Mr. Siamese midi. Their leather, especially he deer nappa, is wonderful, really is top quality. The hardware is real brass (which makes their bigger bags a tad heavy, lol) and the shipping is fast. Another poster had an amazing customer service experience with them. I recommend Deadly Ponies highly.
Hi! I have the monceau as well, and while it's beautiful, I'm questioning the quality. Yours may be different, or I'm not used to this on my bags, but whenever I press down on the edges, like on the logo on the front, something peels away almost from the inside. Sometimes it sounds like glue peeling apart, and now there's a clear dent along the edges, and it's clear that the outer thin layer is just hanging out by itself and separated by the liner. Almost like they put cardboard as a liner to make the bag stiff? The same happened on the back as well.
Is that normal?
