Using your Batman 1989 Grapnel Launcher Prop Replica is easy. First, insert 2 LR1 batteries (you'll need to buy them separately). Then, unfold the handle. To use it, simply aim and 'fire' just like Batman does in the movie. The motorized spool will retract the rope and hook. When you're done using it, make sure to turn it off to save battery life. As for maintenance, keep it away from water and don't expose it to extreme temperatures. Wipe it with a dry cloth if it gets dirty. And always store it in a safe place so it doesn't get damaged. Remember, it may take 2 - 4 working days to dispatch your order, so be patient and get ready to have some fun with your cool replica!
