Official full colour insert compatible with Nucleum®, including the Nucleum: Australia® expansion. The design provides both efficient storage and improved game play. Many of the trays can be utilised during the game, and they greatly aid set-up and clear-away times. The rules and boards act as a lid on top of the trays.

The insert is arranged in up to two layers with space on top for the boards. Note that when fully loaded with the game and expansion the box has room for just one main game board, so adding the Australia board will cause lid lift.
