I'd been storing my Miu Miu bags--I don't know the exact name but they're the sport style with long wide strap in addition to the smaller strap, and they have leather mesh on all sides. I have the black and the gold. I hadn't stored them with paper, and when I tried on the gold, the bottom is a little bent. When I feel it, it makes that cardboard kind of sound.....surely they would use leather and not cardboard. Does anyone know?? Thanks.
