Using these Sentai rings is easy. First, make sure you have the DX Tega Sword which you need to buy separately. Then, just insert the rings into the sword. Once you do that, you'll see cool transformation lights and hear exciting sounds. When not in use, keep the rings in a dry and safe place to avoid damage. Also, be careful when handling them to prevent scratches. That's all there is to it - have fun with your Sentai rings!
