Using this Barbie Display Case Light is easy. First, place your Barbie doll on the stand inside the case. Then, choose the backdrop you like from the two double - sided scene cards and set it up. To turn on the light, you can either connect it to a power source using a USB cable (which you'll need to provide) or insert 3x AA batteries (not included). When it comes to maintenance, keep the case clean by gently wiping it with a soft, dry cloth. Avoid using harsh chemicals as they may damage the case or the scene cards. Remember, the doll is not part of the product, so handle it separately. Also, when not in use, store the case in a cool, dry place to prevent any damage.
