The Heirloom Box is a highly sought after peace of Tom Kuhn yo-yo history. There were many different variations of the Heirloom Box between the 1980s and the 1990s. The two main versions were the large one (pictured here), which held between 15 and 13 yo-yos and the smaller one, which held 6 yo-yos. The large one had a few different logo variations on the lid as well as a few variations on the inside of how many yo-yos could be held in the case.
