open box
A white box (or glass box, clear box, or open box) is a subsystem whose internals can be viewed but usually not altered.
Having access to the subsystem internals in general makes the subsystem easier to understand but also easier to hack; for example, if a programmer can examine source code, weaknesses in an algorithm are much easier to discover. That makes white-box testing much more effective than black-box testing but considerably more difficult from the sophistication needed on the part of the tester to understand the subsystem.

Did I receive an open box item from MidwayUSA? I paid for a new unit.
I ordered a scope from MidwayUSA and I received it this morning. To me this looks an open box item, not a new scope. The scope does look new, but the retail box was not wrapped (don't all new scope retail boxes come sealed?), scope itself was in an open plastic bag and there was no any packing...- Discussion Thread
