Using this ILI Expandable Crossbody is a breeze. First, unzip the top closure to access the main compartment. You can put your phone, wallet, keys, and other essentials in the interior pockets for easy organization. The back slide pocket is great for quickly grabbing items like your transit card. To expand the bag, simply unzip the bottom zip. When carrying, adjust the 22 - inch strap to a comfortable length. As for maintenance, keep it away from sharp objects to avoid scratches on the smooth leather. Wipe it gently with a soft, dry cloth regularly to keep it looking its best. If it gets wet, let it air dry naturally. And remember, don't overstuff it to maintain its shape.
