Using these photo frames is super easy. First, choose the photo you want to display and decide whether you want a horizontal or vertical layout. Then, carefully insert your 4'x6' or 5'x7' photo into the appropriate frame. You can place these frames on a table, shelf, or hang them on the wall to add a coastal touch to your space. As for maintenance, simply use a soft, dry cloth to wipe the frames regularly to keep them looking clean and shiny. Avoid using harsh chemicals or abrasive materials as they may damage the aluminum finish. And be gentle when handling the frames to prevent any dents or scratches.
