This case is versatile, perfect for stationery, smartphones, small tools, and more. It has two pockets, front and back. The front has holders for glasses, pens, etc. (I personally find the glasses holder very convenient.) Dimensions: Height: Approximately 20 cm Width: Approximately 20 cm Depth: 3-3.5 cm It easily fits a paperback book or an A6 notebook. With dimensions of 20cm by 20cm, it offers plenty of space. The leather is oil-finished vegetable-tanned leather. It has a very attractive, subdued brown color. Because it's oil-finished, minor scratches can be rubbed away. Don't worry about scratches or dirt; use it freely and let it develop character. A commercially available, inexpensive shoulder strap is included. Feel free to replace it with one you prefer. You could also remove the shoulder strap and use it as a bag-in-bag. *The system notebook is not included. It's pictured with an A6 size for size comparison. *This product is called "Kanae Square." The leather may change, but the Kanae series will also include a vertically long "Recta" and a smaller "Slim" version. #Sacoche #Pochette (small bag) #SmartphoneCase #ToolCase #MultiCase #BagInBag === This item is from a prototype provided by a workshop I'm acquainted with. Although I'm selling new, unused items, there may be some scratches or stains inherent to the material. Also, the color and texture may not be fully represented in the photos. I've tried to include photos that are as close to the actual item as possible, but please consider the actual item as the priority. I will pack the item carefully, but please understand that I may use recycled materials for shipping. The following is a comment from the workshop: === This item is a prototype. Characteristics of a prototype include: - Items with a strong presence - Items where we want to test the texture - Items where we want to experiment with color combinations At this stage, the craftsmen choose the materials based on their individual preferences. The theme is "Enjoying the appeal of leather with simple functionality." To prioritize the creation of the image, fine finishing touches (such as edge processing and decoration) may not be applied. However, due to fewer restrictions, the designs and functions vary, making them almost one-of-a-kind. Normally, prototype versions are for staff use or distributed to related parties, but they may also end up in storage. We decided to offer them to those who appreciate them. We hope it reaches leather lovers.
