Using this Optimus Prime Smash Changer is super easy. To convert it from alt mode to robot mode, just perform 3 smashing motions. Each smash will activate a conversion step. When you want to change it back to alt mode, you'll need to do it manually in 11 steps. Make sure to handle the toy gently during the conversion process to avoid any parts breaking. After playing, store it in a dry place away from direct sunlight to keep its colors and parts in good condition. Don't expose it to extreme temperatures as this might damage the plastic. Have fun with your Transformers toy!
