This Champion Belt branded 2x piece exercisers for a steel like grip …. handgrip that is. There are 2 identical pieces in the original box. This produced was made around 1970 in Japan. They hardly seen any use. Box is complete as well with one small tear on the side. The red handles are wood, the springs are nice and shiny. The box measure about 15 cm or 6 inches wide. Goes great with our chest muscle trainer!
