This is an Orobianco nylon backpack. The color is navy, and I purchased it about 5 years ago at Isetan. It also has a carry-on bag strap, so I used it once for travel and then stored it in the closet. Therefore, it's in good condition with little wear. However, as you can see in the 5th and 6th photos, one of the two front zippers has gone missing. I think there shouldn't be any problem if you use the other zipper, but please be aware of this. This backpack uses high-density nylon from the Limonta company, which has a history of over 100 years and was founded in the Lombardy region of Milan, Italy. The back has a zipper that allows it to be set up on a carry-on bag, making it easy to carry even while traveling. In addition, the shoulder straps have cushioning material, providing a comfortable fit even for long periods of use. There are 3 zippered pockets and 1 magnetic pocket on the outside, and 1 zippered pocket on the inside, which is convenient for organizing small items. Width: Approximately 28cm, Height: Approximately 52cm, Depth: Approximately 15cm I believe the model name is NELFRATTE.
