Using this product is easy! First, take out the Mini Battling Warrior and the Battle Controller from the pack. You can use the Battle Controller to control your warrior during battles. When it's time to fight, release your warrior's fury and use the new weapons to defeat your opponents. Make sure to keep an eye out for the legendary 'Beast Blade' while collecting the warriors. As for maintenance, keep the warrior and the controller in a dry place. Avoid dropping them or getting them wet. If they get dirty, you can use a soft, dry cloth to clean them gently. Have fun collecting and battling!
