First up is the player box inserts/trays. There are 5 of them and each holds all the necessary pieces for each players setup, They are designed so the plastic insert that comes with the game fits down over these trays. They are made of Draftboard (an engineered wood product - It has an external feel like paper but is as rigid and durable as wood) with Acrylic lids to keep pieces from flying about. The acrylic lids are laser engraved with an architecture/building motif. The pieces come with protective tape on both side. This serves to protect the surface from smoke damage from the laser as well as to protect it from marks during shipping.
