This is a backpack with a unique design, typical of the Spanish brand Camper. It has been used a few times, but there are no noticeable stains. The inside is also clean. When folded flat, it measures approximately: Height: 47cm Width: 20cm Depth: When the side pleats are expanded, it expands to 25-30cm. It has been used a few times, so please refrain from purchasing if you are concerned. It will be shipped folded. Thank you very much.
