Using these Halloween candy containers is super easy. First, open the back of the container and insert 3 AAA batteries (not included). Once the batteries are in, place the container wherever you like, maybe on a table or a shelf. When someone gets close, the motion sensor will detect them, and the LED lights will flash and make spooky sounds. As for maintenance, keep the container away from water to prevent damage to the electronics. If it gets dirty, you can gently wipe it with a dry cloth. Also, remember to remove the batteries when not in use for a long time to avoid battery leakage.
