Using this SHFU Apple Arms Set is easy. First, if you're using it with SH Figuarts Kamen Rider Baron, simply attach the breastplate to the figure. Then, hold the sword and shield in the rider's hands. The Apple Lockseeds can be placed in a visible spot on the figure for a more authentic look. If you choose to use it with SH Figuarts Kamen Rider Gaim, follow the same process. When it comes to maintenance, keep the set away from direct sunlight and excessive moisture. If it gets dirty, you can gently wipe it with a soft, dry cloth. Also, handle the small parts like the sword and shield carefully to avoid breakage. And remember, the Kamen Rider figures are sold separately, so make sure you have the right ones to use this set.
