Using this cross body bag is super easy. Just put on the strap over your shoulder and adjust it to a comfortable length. Then you can carry your essentials like phone, wallet, and keys inside. When it comes to maintenance, use a soft cloth to wipe off any dirt. Avoid getting it wet for a long time as it might damage the waffle pattern. If it gets wet, dry it naturally. Also, don't overstuff the bag to keep its shape.
