Using this RKF armor is super easy. Just pick up the armor and gently place it on your RKF figure. Make sure it fits well and sits securely. When handling the armor, be careful not to apply too much force as it might cause damage. To keep it in good condition, store it in a dry and clean place. Avoid exposing it to direct sunlight for long periods as this could fade its color. If it gets dirty, you can use a soft, dry cloth to gently wipe it clean.
