Using these bumper pads is a breeze. First, identify the loop - side velcro inside your RB Continental Voyager acoustic guitar case. Then, take the bumper pads with the hook - side velcro and attach them to the desired spots according to your guitar's shape. When using, make sure the pads are firmly attached to avoid any movement during transportation. For maintenance, simply wipe the pads with a dry cloth to keep them clean. Don't use any harsh chemicals as they might damage the velcro or the pads. Also, store the pads in a dry place when not in use to prevent any moisture - related damage.
