THe box has a front wooden cover that goes over the whole thing. Pins do disapear but as said before, the person's card is usually left behind. Most people I find will be honest enough to replace the pin if they destroy or loose it. If I am not mistaken, each pin is about $4 or so.

Geistware, that's certainly a favorite.
Do you have trouble with pins disappearing into the dark reaches of flight boxes?
How are the pins stored when nobody is at the field? One concern I have is we're on public land even though vandalism hasn't been a big problem it's always a possibility. We would need a lockable board to keep the pins in but when something gets locked it automatically becomes irresistible to bust it open to see what's worth locking.
