Thank you for looking! This is the Nelson Nylon Rucksack, released to commemorate the 70th anniversary of Yoshida & Co. It is no longer sold on the official website, so I believe it is a rare item that is difficult to obtain. The dimensions are: Height 50cm, Width 35cm, Depth 16cm. Visually, there is not much sign of use, and overall the condition is very good. However, the metal fitting inside, shown in the 5th photo, has come off due to age-related deterioration, so the button cannot be fastened. But I don't think there are any particular issues that would affect its use. The bottom surface in the 9th photo has some noticeable dirt, but since it's the bottom, it doesn't seem to affect the appearance. There is also a 1-2mm hole near the bottom in the 10th photo, but it's at a level that you wouldn't notice unless you looked closely. Thank you for your consideration!
