Using your NGIL Blue Brooklyn Belt Bag is a breeze. First, adjust the nylon strap to your desired length using the snap - in buckle closure. Then, simply open the zip - top closure to access the main compartment. You can use the long mesh pocket for larger items like a phone or wallet, and the smaller mesh pockets for keys or cards. The back zip pocket is great for quick - access items. When it comes to maintenance, wipe the bag with a damp cloth for light cleaning. Avoid using harsh chemicals. And when not in use, store it in a cool, dry place to keep it in top condition. Be careful not to overstuff the bag as it may affect the zip and the shape of the bag.
