The main material uses CORDURA 1000d fabric, which is made of 1000d 66 nylon yarn in both the warp and weft directions, providing strength against friction, tearing, and abrasion. CORDURA 1000d fabric Size: W240 x H150 x D100 mm I purchased this about six months ago for approximately 6500 yen. I used it about 10 times in those six months. It was a little too large for me, so I am selling it. It can hold 3-4 500mm PET bottles, and a little more. Since it hasn't been used much, I don't think there is any major damage to the appearance, but there are black stains and a 5mm square mark in photos 8 and 9. Please check the photos. Please consider purchasing this item, understanding that it is a used item.
