Using this custom skirt is easy. Just carefully attach it to your SH Figuarts Kamen Rider EVOL Black Hole figure. Make sure it fits well. When handling the skirt, be gentle to avoid any damage. As for maintenance, keep it in a dry and clean place. If it gets dirty, you can use a soft cloth to gently wipe it. Don't use any harsh chemicals or cleaners on it. Also, remember this product doesn't come with the figure, so you need to have your own SH Figuarts Kamen Rider EVOL Black Hole figure to use the skirt.
