Using this product is easy. First, take your time to build the kit according to the instructions. Once it's built, you can start combining the parts to create the cool Gunmax armor. To turn it into the Max Cannon, just follow the simple transformation steps. When teaming it up with SMP J-Decker, make sure the connection points fit well. As for maintenance, keep it away from water and rough handling. If it gets dirty, you can use a dry cloth to gently wipe it clean. Have fun playing with your new Gunmax toy!
