Using this kit is a breeze. First, carefully unpack all the parts. Then, follow the included instructions step - by - step to assemble the robot Zearth and the contract machines of Koemushi and Jiasu. When handling the small parts, be gentle to avoid breakage. After assembly, you can display your finished models on a shelf or your desk. To keep them in good condition, avoid exposing them to direct sunlight for long periods as it might fade the colors. Also, keep them away from dust by using a display case if possible. If they get dirty, you can use a soft, dry cloth to gently wipe them clean.
