I have one like the one in the picture, holds 100 pairs of dice, then I have several bigger ones that will hold 100s of pairs....the shelves have a lip to prevent the dice from falling out. The cases can be hung on a wall or laid flat....best way I found for a dice collection.....I no longer collect dice so need to pass these on....I will be at the Convention on Thursday for one day. I live in Southern California....offers in cash or chips, silver strikes, badges or patches....I want to move these out....thanks Jim (626) 893-7926
