BANDAI's METAL JOE series, MJ-1 Blue Rock. - Brand: BANDAI - Model Name: MJ-1 - Series: METAL JOE SERIES - Product Name: FIGHTER ROCK - Color: Blue I took a lot of pictures, but the lid of the box is sealed with tape. Metal Joe series. Extremely rare. I was able to transform it into a robot and back, so if an old person like me can do it, it should be easy for young people. Please keep in mind that this is an old item, and I would appreciate it if you could judge the condition from the images. The instructions are included. I think this is a very vintage item. It came out of the closet, but I won't be using it, so please take it. Thank you for looking.
