What the club objects to (I hope) is not the size or shape of the container, but the process of professional grading. A graded chip is sealed in a "slab" to prove that the "grade" belongs to that chip.

The chip in this auction has no grade, and therefore I do not view the container any differently from a rectangular cardboard flip with the chip description printed on it, or an AIR-TITE. Am I missing something here?
