This is a thermal bag for delivery. I bought it but never had the chance to use it, so I stored it after using it only once. It's a backpack type, so you can keep both hands free, making it easy to move around during delivery. The inside is aluminum-lined for insulation, making it easy to maintain the temperature of food. Reflective tape is attached to the front and sides, providing good visibility at night. The size is approximately 35L, which is a sufficient capacity for delivery purposes such as Uber Eats. There are no noticeable stains or scratches, and the condition is good. Since it is a no-brand item, please refrain from purchasing if you are concerned about the details. Although it is unused, it has been stored at home, so please understand this before purchasing.
