Using this belt with your DX Evol Driver is a breeze. First, attach the belt to the DX Evol Driver following the standard attachment method. You can adjust the length as needed because it's extendable. When you put it on, make sure the larger buckle and clips fit securely. As for maintenance, keep it away from sharp objects to avoid scratches on the painted surface. If it gets dirty, use a soft, damp cloth to gently clean it. Always store it in a dry place. And remember, the DX Evol Driver is sold separately, so you'll need to have it to use this belt.
