Using this belt buckle is easy. First, slide the belt through the single - lap belt loop. Then, fasten the belt with the automatic buckle. For a secure fit, make sure the buckle clicks into place. When it comes to maintenance, avoid getting it wet in saltwater or harsh chemicals as it may damage the alloy and PU finish. You can clean it with a soft, dry cloth regularly to keep it looking shiny. Also, store it in a dry place when not in use to prevent rusting.
