Using this product is easy. First, make sure you have a CR - 927 battery handy as it's required to power the LEDs but not included in the package. Install the battery according to the polarity markings. Then, attach the head to your SH Figuarts Kuuga Rising Ultimate figure. Enjoy the enhanced look with the reduced red in the compound eyes and the included black compound eye. When it comes to maintenance, keep it away from moisture and dust. If it gets dirty, you can gently wipe it with a soft, dry cloth. Remember, this product is an aftermarket upgrade, so handle it with care. Also, it's only for use with the SH Figuarts Kuuga Rising Ultimate's head which is sold separately. And you're in luck if you're in the USA as it ships for free.
