Using the CSM Birth Driver and X - Unit set is easy. First, take out the Birth Driver and insert the X - Unit into it. Then, you can use the included Cell Medals to bring the set to life. Just like in the show, you can have a great time simulating the actions. When using the Bluray movie, simply insert it into your compatible player. As for maintenance, keep the set in a dry and cool place. Avoid dropping or rough handling the items, especially the Cell Medals as they are small and can be easily damaged. If the set gets dirty, you can gently wipe it with a soft cloth. Enjoy your Kamen Rider collectible set!
