OROTON Bag Leather? Synthetic leather? I'm not sure, as I'm not an expert, sorry. The color is black. There is stitching in a reddish-brown thread, I suppose you'd call it, running vertically along the sides. Inside, there are three pockets, one of which has a zipper. The main body also opens and closes with a zipper. The purchase date and frequency of use are unknown. This item has been stored at home. I believe there is some dullness on the metal fittings and the main body due to storage. Please consider purchasing this item if you understand the above.
