M from forme banks. The leather is Tolso leather. I've used it about 10 times. There are no noticeable scratches on the outside, but there are some scuffs and dents on the inside from putting things in it. Also, as shown in the last photo, there is a light purple stain. I suspect it's from where I kept silver accessories, and something may have reacted with the leather. I didn't spill any drinks on it. Material... Leather
