Using the della Q Maker's Mini Mustard Messenger is a breeze. You can wear it across your back for hands - free movement when you're on the go, or across your chest if you need quick access to your items. The adjustable strap can be set to your preferred length. Just loosen or tighten it to fit comfortably. When you're carrying it by the top handle, make sure not to overload it to avoid any strain on the handle. As for maintenance, keep it away from sharp objects to prevent any damage to the waxed canvas and leather exterior. If it gets dirty, use a soft, damp cloth to gently clean the surface. For the hardware, avoid contact with harsh chemicals as it may damage the antique bronze finish. With proper care, this bag will serve you well for a long time.
