YG Treasure Box (YG 보석함) was a boy group survival reality program developed by YG Entertainment which aired on JTBC2 from November 16, 2018 - January 18, 2009. The show featured 29 trainees competing to earn a spot to debut under YG Entertainment's newest boy group. By the end of the show, 7 trainees successfully became members of the group TREASURE. However, due to public demand, the company has also decided to form a group consisting of 6 eliminated contestants which were then called MAGNUM. It was then announced that the group will be collectively called TREASURE13, with sub-units TREASURE and MAGNUM.
By 2020, YG Entertainment announced that instead of promoting as two different units, the group will promote as one by the name TREASURE.
