Using these Yellow Ranger Power Daggers is super easy. First, get 6 'AAA' batteries and put them in as per the instructions. Once the batteries are in, you can turn on the electronics and watch the blades light up and hear the cool sound effects. You can use them for role - playing just like in the show or display them on the stand to show off. When it comes to maintenance, keep them away from water and rough handling. If the blades get dirty, you can gently wipe them with a dry cloth. Also, when not using them for a long time, take out the batteries to avoid any damage. Remember, this product is for ages 18 and up, so keep it out of reach of younger kids.
