Using the DX Eagle Shooter 50 is easy. First, pull the arrow back. Then, when you're ready, release it to activate the cool gimmick. When you want to form the Tega Sword Green, grab the separately - sold DX Tega Sword and combine them. As for maintenance, keep it in a dry place. Avoid dropping it from high places to prevent damage. When not in use, store it in a safe spot to keep it in good condition. Also, be careful when handling the arrow to avoid any accidental pokes.
