Using this Daizyujin mecha set is super easy. First, take out the 5 core mecha from the box. You can start by combining them to form Daizyujin following the simple assembly steps. If you want more fun, try mixing and matching them with other robos in the Robo Universe line. When playing, be gentle with the parts to avoid any breakage. After you're done playing, store the mecha in a dry place away from direct sunlight to keep them in good condition. Also, keep small parts out of reach of young children to prevent choking hazards.
