To use this product, simply take the 5 core mechas out of the box. You can combine them together to form Gaoking following the easy - to - understand combination process. You can also get creative and mix these mechas with other Robo Universe line robos. When handling the mechas, be gentle to avoid any parts breaking off. Store them in a cool, dry place when not in use. If any dust accumulates on the mechas, you can use a soft, dry cloth to wipe them clean.
