This Bridgestone yo-yo & GO! BICYCLE wristband set was a Japanese bicycle-themed novelty item packaged under the Bridgestone name. The set includes a terry-cloth wristband and a cheap yo-yo decorated with a bicycle wheel design and the Bridgestone logo. The wristband also carries the GO! BICYCLE mark with a penny-farthing-style bicycle graphic, tying the yo-yo directly to cycling imagery. It's unclear whether this set was sold retail (does not have a UPC code) or, more likely, given away as a promotional item.
The item reflects Bridgestone's wider bicycle identity exclusively in Japan. Bridgestone Corporation lists bicycles among its business areas, and Bridgestone Cycle still offers bicycle catalogs, accessories, and related product information.
