Thank you for viewing. This item was used by my child, but has been kept at home since they no longer play with it. Also, please understand that the outer box is not included before purchasing. Here is the product information: When you set the Sentai Gear on the front and turn the handle, the Sentai Gear and the barrel rotate, and pulling the trigger transforms you into Zenkaiger! Furthermore, by setting the back of the Sentai Gear, you can also play with the giantization and combination commands of the robot hero. 5 Sentai Gears are included. It also works with separately sold Sentai Gears, allowing you to enjoy various sounds. The Zenkai Buckle can store up to 6 Sentai Gears. Requires 2 AAA batteries (sold separately)
