Global Work Boston bag. I've marked this as "defective" because it's missing the shoulder strap. The main body is in almost unused, beautiful condition, but the shoulder strap is not included. You can still use it without the strap, but I think it might be inconvenient, so I will include a shoulder strap purchased from Seria. Please see the last photo. I also use it on another bag, and it's durable and convenient. Please consider this item only if you understand the defect. I am very sorry. Now, about the main body: it's a lightweight, water-repellent, and durable nylon bag. It has an elegant satin material, a simple design, and white parts and logos that accent the unisex design. It has a double-zipper structure that opens wide for easy loading and unloading of luggage, as well as an outer zipper pocket and various inner pockets. The handle pass-through that can be fixed to a carry-on handle is convenient for those who use carry-on cases. There are many convenient features, such as a carabiner hook inside the pocket for attaching keys, making it useful both when traveling and in everyday life. It can be used in 3 ways: hand-held, shoulder-carried, and crossbody (using the shoulder strap). The GWGG logo is used to emphasize practicality, durability, and functionality (water repellency, nylon) rather than fashion, and it stands for GLOBAL WORK GOOD GEAR (= good gear as a tool that can withstand daily use and travel). The size is 31.0cm in height, 46.0cm in width, 20.0cm in depth, and 69.0cm for the handle. Although it is defective, it is a very beautiful item. It is the size of a home delivery service, not Yu-Packet. Therefore, the shipping cost will be slightly higher, so I cannot offer much of a discount. Thank you for your understanding.
