e-Raptor Organizer compatible with Terraforming Mars is a perfect accessory designed to organize and improve gameplay of the board game.
The organizer allows you to put cubes into special tracks to keep your production values in order. The tracks have special little insets to hold cubes (not too tightly, though you can still move them). The rest of counters wont slide off the players board as well.
You can hold all your stuff in one place without being afraid of losing control of the setting and your resources.
It's made of transparent plexiglass and first grade High Density Fibreboard.
