LOUIS VUITTON MONTSOURIS BB UPDATED REVIEW! 1.5 YEARS + WEAR 。Authentic, vintage Louis Vuitton Montsouris Backpack. The main body of the backpack features iconic LV monogrammed coated canvas. The trimmings are calfskin vachetta leather at the base, trim and straps. Pre-owned. Coated canvas is in excellent condition but the vachetta leather not so much. The leather is cracked and water staining on the bottom. If you’re crafty and make things like phone covers, planner covers etc then this may be the bag for you! This bag has been authenticated several times! See photos. This is the small size.
