Our organizer for Aquatica is composed of ten trays. It will hold the base game and the Cold Waters expansion all within the main game box. It stores  sleeved cards. I used Gamegenic for the standard-sized King and Character cards and Swan 50x100 thin sleeves (cut down) for the smaller Location cards. It have separate player trays for quick and easy distribution at the beginning of each game. (Game not included)
