Using this dice case is super easy. First, open the case and place your dice on the side designed for storage. When it's time to roll, you can either use the built - in tray at your own spot or pass it around the table for others to use. As for maintenance, simply wipe the case with a soft, dry cloth regularly to keep it clean. Avoid dropping it from a height or subjecting it to rough handling, as this could damage the reinforced structure. Also, don't use sharp objects near the soft - lined interior to prevent scratches on your dice.
