Bonmamon vertical bag-in-bag. The color is light gray. It's a slim type with 7 pockets, allowing you to effectively utilize the vertical space in your backpack or tote bag. You can also fit a lunch box and other items in the empty space. The mesh material makes it lightweight, so it's attractive because you can carry it without stress. Comes with a drink holder. Purchased last year from Ange. I've used it a few times, but I'm selling it because I started using something else. The condition is good. Please understand that this is a used item before purchasing. 【Specs】 Size: Height 33.5 x Width 25 x Depth (maximum width) 5.5cm Weight: Approximately 75g Material: Nylon, Polyester
