Thank you for viewing. This is an INCASE backpack for sale. I purchased it as an authentic product and owned it for about 2 years, using it once or twice a month, but I am selling it because I bought another backpack. In my amateur opinion, it's still in good condition and usable. There are no zipper malfunctions or any noticeable damage. City Collection Compact Backpack Retail price: ¥18,700 #backpack #bag
