Alexander Wang Prisma backpack

Alexander Wang Prisma backpack. Made with canvas, calfskin leather and suede. The bottom of the bag is made with suede. I used to dropped the bag on floor and suede puckup dirt easily it does has stains. Think it can be removed by suede cleaner. Other than that it's in good condition. One exterior zip pocket on the back, one interior pocket. Please refer last photo for dimensions.
