This is a LOUIS VUITTON Montsouris GM. I purchased it at an authorized store (Sapporo City). It is guaranteed to be authentic. It's a rare backpack that remains popular even now that it's discontinued. I purchased it over 10 years ago, so there is some aging, but it hasn't been used much. This is an expensive item, so please check the images and only purchase if you are satisfied and understand that it is a used item. To prevent switching, returns and refunds are not possible under any circumstances. NCNR (No Claims, No Returns) - thank you.
