Using this storage case is easy. Just open the spring - loaded, recessed catches and place your items inside the foam - lined protective interior. The heavy - duty locking casters make it simple to move the case around. When you're done, close the catches to keep your items secure. As for maintenance, you can wipe the exterior with a damp cloth to keep it clean. Avoid using harsh chemicals as they may damage the ABS plastic laminate. Check the rivets and hardware regularly to make sure everything is in good condition. And when not in use, store the case in a dry place to prevent the plywood from warping.
