Back in the early 80s Bosch sold these Japanese made caps in blister packs, made to be hung on the display wall. They didn't sell very well and eventually Bosch offered these at a discount and we bought all we could, and we took them out of the blister packs and put them on the shelf in bin boxes. These are made in Japan by the companies that made them for the factories that made the cars.
