A plastic ballbearing yo-yo from BMT, a company in Kansas City, MO. This company was better known for their unique aluminum yo-yos. Each halve has a raised relief of eight spider legs and a head. The body is the bulging axle hub area.
BMT eventually ceased yo-yo production sometime in the early 2000s (which was around the same time period that the yo-yo boom ended in North America and Japan) . As of late 2017, BMT was still in business as a one man machine and other job shop.
