This is a bag from m.a+ (m.a+ cross). It is made of 1.0mm thick vacchetta leather, and as you use it more and more, you will see changes in the color and softness of the leather. When viewed from the side, the leather is folded like an accordion, a characteristic design. The folded part of the leather can be opened up to make the opening wider when putting things in and out of the bag. There is no clasp, and the bag opens and closes with a flap. The inside is unlined and simple, with one zipped pocket on the inside.
