Not to be a thread buzzkill, but a lot of times people just take out the diapers to make sure they are the correct design, fit, whatever.
That was my hopeful contribution, too.
Although I *do* like the idea of "boxes CLOSED, one provided by the store out for demo" that was brought up. Nothing quite beats seeing the real thing...
That said, though, I pull *phones* and *electronics* out of their (not-sealed) box for a "feelie" before I buy. I sure as heck wouldn't pull anything out that had a sanitation element to it (food, toothpaste, mouthwash, pads/tampons, diapers, etc.) - that's just ... awful.
*Goes to throw up a bit more*
