Skip, I use the super shoes for just about everything. They are also great for storing decks of playing cards (holds around 75 decks).

If you take the 3 inserts out, you can store "flat items", I have one that I store my "win cards" chip packets in.

You might also buy a few of the sorting boxes, they come in handy when you are trying to sort slot club cards by location/casino.

If you collect Hot Wheels cars, by the standard shoe box, take the insert out and the box will hold around 20 - 30 cars on their cards.
