To use these mechas, first take them out of the box carefully. You can play with each mecha separately or combine them into a bigger form. When combining, just match the parts as shown in the picture. Be gentle when handling the small parts to avoid breakage. To maintain these mechas, keep them away from water and dust. You can use a soft cloth to clean them occasionally. Don't expose them to direct sunlight for a long time, as it may fade the colors.
