Thanks Karl, yep I hope to start a trend with those boxes!
Thanks Vladimir, actually the bottiom of these box is removable with some small screws, it's very convenient for maintenance.
I have been told that at some fairs, the judges take the dioramas and turn them upside down, if anything falls on the floor then the dio is disqualified, well I have been shaking these dioramas so that I never have some small bits lying at the bottom!
