Using this utility belt is easy. First, pick your favorite cartridges from the eight provided and place them in the four slots on the belt as you like. To attach additional gadgets like the Batarang, just use the magnetic feature on the front of the belt. Remember, the Grapnel Launcher and Communicator are sold separately. When it comes to the removable face plates, you can take them off to show the hidden tools. For maintenance, keep it in a dry place away from direct sunlight. Avoid getting it wet as it might damage the magnetic parts and cartridges. When adjusting the belt in the back, make sure not to over - tighten it to prevent any damage to the buckle or the belt itself.
