I used this once for hiking and stored rainwear in it. I don't think there are any scratches or stains, but please understand that this is a used item. Product Description: This is a waterproof bag with a flat-bottom design that achieves extremely high waterproof performance. If you cinch the bottom with a string through the strap holes, the bottom becomes triangular, making it easy to put in and take out of a kayak hatch. It has extremely high waterproof performance, but please note that it is not suitable for use underwater. Specifications: [Material] Polyester Tarpaulin [Weight] 150g [Color] Clear (CLER) [Size] 25 x 40cm [Capacity] 5L
