Using this crossbody bag is super easy. Just open the zipper or twist lock closure, put your things inside, adjust the strap to your preferred length, and you're ready to go. When carrying it, make sure the strap is securely on your shoulder to prevent it from falling. As for maintenance, keep it away from sharp objects to avoid scratches. If it gets dirty, you can gently wipe it with a soft, damp cloth. Don't expose it to direct sunlight for a long time as it may fade the color. Also, store it in a cool, dry place when not in use.
