Our organizer for Nidavellir is composed of twelve trays and will hold not only the base game, but also the Thingvellir expansion both within the main game box. It will house premium sleeved cards. There are five individual player trays to store each one's beginning coins along with a larger tray that will hold the coin storage display while assembled (I glued mine and stored it in this tray with the larger boards placed underneath). (Game not included)
