Using this Black Panther electronic helmet is a breeze. To start, put the helmet on your head. The adjustable interior padding allows you to find the most comfortable fit. Once it's on, you can press the button on the side of the helmet. This will trigger the Vibranium - inspired light FX, just like in the movie. To use the flip - up/flip - down lenses, simply touch the relevant button, and they'll do their thing. When it comes to maintenance, keep the helmet in a dry place. Avoid exposing it to water or extreme heat. If it gets dirty, use a soft, dry cloth to gently wipe it. Don't use any harsh chemicals as they might damage the helmet's details or electronics. Also, be careful when handling the buttons and lenses to prevent any breakage. Have fun pretending to be the Black Panther with this amazing helmet!
