This is the SUS YOYO MECHANICS - Generator Silver. It's a bimetal model redeveloped based on the first model, "SUS-001." The retail price was around 12,000 yen. The exterior has no noticeable scratches and I think it's in beautiful condition. The bearing has been changed from a Center Trac bearing to an unnamed concave bearing. I don't think there's any wobble, but since it's a used item, please consider there might be a slight wobble. I've taken a lot of photos, so please check them before purchasing. m(_ _)m I will disassemble it for shipping. Manufacturer: SUS YOYO MECHANICS
