Using this Iron Spider helmet is a blast! First, make sure you have 2 x 1.5V AA alkaline batteries (they're not included, so grab them from your local store). Once you've inserted the batteries, turn on the helmet and you can start playing around with the 6 different light settings for the LED eyes. You can choose between red and blue lights on low, medium, or high. To put on the helmet, just adjust it to fit your head - it's made to fit most adult sizes. When you're done using it, turn it off to save battery life. Store the helmet in a cool, dry place to avoid any damage. And remember, if you have any issues with epilepsy, be careful as the LED lights might cause problems.
