This backpack is super easy to use. Just unzip the main compartment to store your essentials like books, a laptop, or your daily items. You can also use the smaller pockets for things like keys or your phone. When it comes to carrying, the adjustable straps make it comfortable to wear on your back. As for maintenance, spot - clean the denim with a mild detergent and a soft cloth. Avoid getting the metal parts wet for too long to prevent rust. Also, keep in mind the California Proposition 65 warning about the chemicals in the product, so don't let it come into direct contact with food or sensitive skin for extended periods.
