Using your Super Minipla Bio Robo set is easy. First, take out Bio Jet 1 and Bio Jet 2 from the box. You can play with them separately as cool jets. When you want to combine them into Bio Robo, just follow the connection points on the models. Make sure to align them properly for a secure fit. As for maintenance, keep them away from sharp objects to avoid scratches. If they get dirty, you can use a soft, dry cloth to gently wipe them. Also, store them in a cool and dry place when not in use. And remember, since it's a pre - order item, be patient for the February 2021 release date. Enjoy your playtime with this awesome set!
