Using this Optimus Prime Smash Changers figure is super easy. To convert it from alt mode to robot mode, just perform 3 smashing motions, and each motion will activate a conversion step. To go back to the alt mode, you'll need to do it manually in 11 steps. When playing with the figure, be careful not to use too much force while smashing, as it might damage the toy. Also, keep it away from small children who might put parts of it in their mouths. For maintenance, you can use a dry cloth to wipe off any dust. Store it in a cool, dry place to prevent any warping or damage. Have a great time transforming and playing with your Optimus Prime figure!
