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. Note that in the player trays the player's urban building tiles need to be stacked in one corner.

The two experiment tile trays have room for the eight technology tiles per experiment. You can alternatively keep these tiles inside the experiment boards, however we found that they tend to fall out during storage. Every tray includes images from the rulebook or game cards and boards. There is one unusual tray for the game cards and action tiles. This tray has no base on the back where the cards go in order to provide room for sleeved cards.

The images greatly improve the look of the trays, but also help in game clear up as you can instantly see what goes where. When packing the box, first place the main board on top of the lower level of trays. This is followed by the side board and rule books. Next place the player board on top of everything, and lastly add the experiment boards and general player aids as shown. This fully fills the box without any lid lift (assuming a single main game board) and allows for vertical storage of the game.

This product consists of a flat-pack of 4 Evacore sheets. The trays require assembly, which is quick and fun, using ordinary PVA glue. Detailed instructions are included in the package.
