This is an ARTPHERE BAG from Toyooka Kaban. It's an ARTPHERE bag designed by Mr. Yuri. I loved and took good care of it, so it's in beautiful condition. I used it as a hand-held bag and didn't use the shoulder strap. When I was listing it, I looked for the shoulder strap but couldn't find it, so I'm offering it at a lower price. If you'd like to use it as a shoulder bag, you can purchase a shoulder strap of your choice. The size is approximately 25 cm in height, 34.5 cm in width, 14.5 cm in depth, and the handle drop is about 5 cm. It easily fits A4 documents, and the back zipper connects to the inside, making it easy to take things in and out. I hope to pass it on to someone who will use it.
