Using this Optimus Prime action figure is super easy. First, to convert it from robot to truck, find the panel on the chest and slide it down. Then press the cog, and it will automatically change in one step. When you want to limit the conversion, use the cog lockout feature. As for care, keep it away from sharp objects that could scratch the figure. If it gets dirty, you can use a soft, dry cloth to gently wipe it. Don't immerse it in water as it may damage the internal mechanism. And remember, other Transformers toys are sold separately, so you can collect more to build your own collection and have even more fun staging battles.
