Using the Delphine bag is a breeze. To use it as a clutch, simply hold it by the top. For a crossbody style, attach the strap and adjust it to your preferred length. When you're not using it, store it in a cool, dry place away from direct sunlight. Avoid contact with sharp objects that could scratch the leather. To clean it, use a soft, damp cloth and gently wipe the surface. Don't use harsh chemicals as they can damage the leather.
