Using these bumper pads is a breeze. First, open your RB Continental Voyager guitar case. Then, take the bumper pads and match the hook - side velcro on the pads with the loop - side velcro inside the case. You can move them around to fit the shape of your electric or bass guitar. When it comes to maintenance, keep the pads clean. You can use a soft, dry cloth to wipe them down. Avoid using harsh chemicals as they might damage the velcro or the pad material. If you notice the velcro isn't sticking well over time, you can try gently brushing it to remove any debris. Also, when not in use, store the pads in a dry place to prevent any mold or mildew growth.
