To use this set, start by carefully taking out the kits from the package. Then, follow the step - by - step instructions to assemble X Emperor Slash and X Emperor Gunner. Be gentle when handling the small parts to avoid breakage. When you're not using the assembled toys, store them in a dry and cool place to prevent any damage. If there are any dust or dirt on the toys, you can use a soft, dry cloth to wipe them clean. Don't expose the toys to direct sunlight for a long time as it may cause color fading.
