Using this Kamen Rider Gears Sound Core ID Set 05 is super easy. First, locate the switch on the Core ID. Flipping this switch will let you enter the mode to play the show's BGM and enjoy the awesome music. You can place the Core IDs inside the DX Desire Driver, but remember the driver is sold separately. When it comes to the set, it includes tops for Geats, Tycoon, Buffa, and Nago, but only two bases in Geats and Tycoon colors. As for maintenance, keep the set in a dry and cool place to prevent damage. Avoid dropping or rough handling. If you want to clean it, use a soft, dry cloth. That's it! Have fun with your new Kamen Rider collectible.
