Authentic Louis Vuitton Christopher Backpack

I am selling this Louis Vuitton Christopher Backpack. It is 100% authentic. I bought it a couple of years ago as a huge birthday present to myself. Because of the price I was always very hesitant to use it so it is pretty much in mint condition. I would love to keep this piece, but I need the money to go somewhere else. Last month my mom was diagnosed with stage 4 cancer, and my brother and I are trying to come up with money to pay for all of the things not covered by her insurance.
