Using this Doc Brown action figure is a breeze. You can change the heads and hands easily to create different looks for the character. Just gently pull off the existing head or hand and replace it with the one you want. The case of emergency cash and binoculars are great accessories that can be placed in Doc Brown's hands. When it comes to maintenance, keep the figure in a dry place away from direct sunlight to prevent color fading. Also, be careful when handling the small parts like the interchangeable heads and hands to avoid losing them. And that's it! Enjoy playing with your awesome Doc Brown action figure.
