This newly revised storage system, although able to efficiently hold the retail version of the game, was designed specifically to hold the game with the Meeple Source upgraded components. The insert is composed of (6) removable trays. One of the trays is used to hold the commonly used game pieces (ie workers and money) while others are designed to hold the upgraded ships; carefully separating them to preserve the colors. Meeple Source has many different upgrade kits for games! (Game not included)
