I've used it a few times. Please refrain from purchasing if you are looking for a perfect item. This is a large-capacity body bag equipped with many pockets and bottle holders, and can fit A4 size items (though just barely). It's perfect for those who usually carry a lot of luggage, as well as for commuting, going to school, use as a mother's bag (lots of pockets! There are also two bottle holders!), "oshi-katsu" (putting stuffed animals in the large front mesh pocket is cute!), live events, events, outdoor activities, and more! It's a design that can be used by both men and women, so it can be shared. The thick and sturdy belt doesn't dig into your shoulder and distributes the weight. The size is also easily adjustable. It also secretly has a suitcase belt! You can easily attach it to the handle of a suitcase, making travel comfortable. The removable micro pouch is also convenient for storing small items like coins and earphones! Size: Approximately 42cm wide, 27cm wide at the top, 21cm wide at the bottom, and there may be some slight variations. Shoulder strap length is approximately 60 to 130cm. I am also selling this on other platforms, so please contact me before purchasing. If you purchase without contacting me, your order may be cancelled. As far as I can see, there are no noticeable stains, but this is only based on my observation, so please refrain from purchasing if you are looking for a perfect item.
