I hate to mention the obvious...but
Has anyone used the 12" x 16" small glass display cases that CT Rogers sells ($17.50)? The felt lined 35 space 2"x2" insert will hold 70 pair of dice. Strips of paper will keep the dice from touching and you can read the name of the casino through the glass top. One elevated, not so important die in each corner keeps the glass lid form touching the other dice tops. Easy to store as they stack on one another. Maybe I'm late to the game and don't understand the problem.
