Convenient Virus Backpack I impulsively bought this a few years ago when it was imported to Japan in limited quantities, but I only used it once for a short time and then stored it for a long period. It can hold a PC and lunch, making it suitable for work, and it can also fit shoes and workout clothes, making it very practical and versatile. Recommended for gym-goers and trainees. Also great for business trips and travel!! The body surface has a light waterproof function, and it also has water-stop zippers. It has higher durability and functionality than other companies' backpacks. *Functionally, there are no problems, but the aluminum part of the lunch storage area is slightly peeled off. No returns or claims accepted.
