This is a ZOMAKE 25L foldable backpack. It's a lightweight backpack that folds up compactly. It can be used for travel, as a sub-bag, for disaster preparedness, and more. 【Capacity】 Approximately 25L 【Size (when expanded)】 Height: Approximately 41cm Width: Approximately 27cm Depth: Approximately 20cm 【When folded】 Approximately 17 x 14cm, palm-sized 【Weight】 Approximately 0.29kg (approx. 290g) 【Condition】 There are some stains, fraying, and scratches from use. Please check the photos. There are no problems with use, but please refrain from purchasing if you are concerned. Although it is a foldable design, I usually used it without folding it, so there are creases and shape distortion. It will be folded for shipping. Please purchase only if you understand that this is a used item.
