The Unbroken Bonds Build & Battle Box is a special product given to participants at the start of Prerelease Tournaments for the Unbroken Bonds expansion. These tournaments were held on the two weekends prior to the release of the expansion: April 20-21, and 27-28, 2019. The boxes were later made available to purchase at retail stores. Each box contains a random set of predetermined cards designed to enhance the experience of the Limited format events in which they were initially distributed.

The Prerelease cards for the Unbroken Bonds expansion are Volcanion, Persian, Stakataka, and Melmetal, with each containing a group of Pokémon cards that are focused around the following types respectively: Fire-type, Water-type, Fighting-type, and Metal-type.
The Unbroken Bonds Build & Battle Boxes provided exclusive Non Holofoil versions of cards only available as Holofoil in Unbroken Bonds booster packs: Lucario and Red's Challenge.
Each Build & Battle Box included two of the following four different groups of Pokémon cards, with one group always coinciding with the included Prerelease promo.
Each Build & Battle Box also included an additional random group of 4 of the following Supporter cards, with no more than 2 copies of a particular Supporter.
