Using this Heartstealer sword is a breeze. First, load a Nerf Elite foam dart into the sword. Then, pull down the priming handle at the end of the sword. Finally, press the button to fire the dart. When playing, it's recommended to wear eyewear (not included) to protect your eyes. After use, keep the sword and darts in a dry place to prevent damage. If the darts get dirty, you can gently wash them with mild soap and water and let them dry thoroughly. This toy is great for kids aged 8 and up, both boys and girls, and is suitable for both indoor and outdoor play. Have a blast with your friends and family in Minecraft adventures!
