Using this awesome RIKI-OH mecha is super easy. First, unfold the mecha from its box shape. You can play with each piece on its own or start combining them to form the big robot. Just match the parts carefully and they'll fit together nicely. When you're done playing, fold the mecha back into a box and store it in the Storage Box. Here are some things to keep in mind. Be gentle when handling the diecast and plastic parts to avoid any breakage. Don't try to force the parts together if they don't fit smoothly. To keep your RIKI-OH in great shape, keep it away from water and dust. You can use a soft cloth to gently wipe it clean if it gets dirty. Enjoy your RIKI-OH mecha and have a lot of fun!
