This is a MONOLITH crossbody shoulder bag. It's simple, easy to match with any outfit, and highly functional, making it perfect for work. Although it looks slim, it's convenient as it can securely store items other than a laptop. The shoulder strap is removable, so it can also be used as a bag-in-bag or a PC case. It is currently sold out on the official website, and the retail price was ¥33,000. There is a warranty card from February 2023. Although it has expired, I will include it. https://www.monolithpack.com/shop/g/gM-PR-4017-11-010 Material: Nylon Color: Black Pattern/Design: Plain Bag Size: 360 x 270 x 17mm, A4 size compatible
