Using this bag is super easy. Just adjust the shoulder strap to your comfort level and sling it across your body. You can store your phone, wallet, keys, and other small items inside. When you're out camping or hanging with friends, this bag will be your perfect companion. As for maintenance, use a soft, dry cloth to wipe off any dust or dirt. Avoid getting it wet for a long time, as it's made of polyurethane. Also, don't over - stuff the bag to keep its shape. Since it's an official Disney product, handle it with care to keep those cute Stitch and camping details looking great.
