^Not exactly. Regular is box pressed, cabinet is round (at least the ones I've seen...and purchased).
However, not all of them come in cabs of 50. The box of double coronas I bought at an event weeks ago was either 20 or 25. I'd check to see which, but I need to go get some lunch.
BTW, just smoked another one of the cabs night before last. Great smoke. I've got a box of the regulars, too (corona gorda vitola, IIRC). I prefer the cabinet series. However, that one box set me back over two Bengamins (but I did get some nice schwag with them, including three tat blacks).
