Okay, I need someone with some expertise to help me on this one. I bought 39 MM air-tites to hold my $5 Chips, but they will not accomodate the Chips with Metal centers as the chips are just a shade too big. So, I went in search of a slightly larger size. A guy sold me a bunch telling me they were what I needed for the larger chips, and they work, but they are HUMONGOUS, 52MM in diameter with a fo am ring insert. Is there not a size of Air-tite I can buy that will fit the metal centered chips snugly without the ring??
