Well, there's always the chance of that no matter what the prop - that goes with the territory I'm afraid, but it shouldn't be enough to stop someone doing a run of something, IMO.

Anyway, no sweat - it's your box and you are free to do as you choose of course. 'Twas just an idea.
Nice work, BTW - I especially like the recessed coin slots.:thumbsup
