This is an EVERWIN dalles bag (backpack type). The difference between a dalles bag and a regular bag is that it opens with a single touch, like a clasp, making it easier to open than those with zippers or belts. It's large enough to easily fit A4 files. The design is suitable for both men and women. According to the manufacturer's website, it uses "highest quality Z-calf," which seems to be top-of-the-line synthetic leather. It has a smoothness similar to calf leather and is completely different from ordinary synthetic leather. The list price, or rather, the price on Amazon at the time of listing, is 34,800 yen, so this is 1/10th of the price. It has been used to some extent, so there are scratches on the corners and stains on the canvas fabric, but I don't think there are any problems in practical use. The stains on the canvas fabric can probably be removed to some extent by washing. Please understand that this is a used item due to the 1/10th price and the "scratches and stains." Shipping will likely cost over 1,000 yen, so I'm not considering lowering the price at the moment, but I have it set to decrease by 100 yen every day. If it doesn't sell by June 30th, it will be discarded. Color: Beige
