I've heard that Tuscania can be a little delicate, similar to Balenciaga's Agneau leathers. My old Bal bags seemed to show wear on the bottom corners pretty quickly, but I believe that Tuscania is calfskin rather than lambskin so it could be tougher. Have you noticed any wear on your Midi Muse?
Not really, just very slightly dulled on the corners. As it already has a distressed finish, I find a regular treatment with leather cream restores it. It stands up to getting wet, I had to go out in heavy rain today and you wouldn’t know now.
