I bought this for my son's outdoor activities. It's been used, but I think it's still usable, so I'm putting it up for sale. Please note that the dimensions are approximate, as they were measured by a layman. The red-boxed area in photo 5 originally had a small, detachable knapsack, but it has been lost. The inside is in relatively clean condition. Photo 9 shows the zipper open to increase the backpack's capacity. The ✨️ mark has my name written on it, so I've blacked it out before shipping. I plan to compress it for shipping. This is a multi-functional blue backpack, perfect for outdoor activities and travel. - Color: Blue - Design: Backpack style - Size: Approximately 50cm x 40cm Thank you for looking.
