in this thread there is an interesting discussion about how to tell the real ones http://forums.azbilliards.com/showthread.php?t=427909
jazznpool ( martin from superiorcues )posts here on azb
and joerackem /neilsen's billiards (ebay)
have reputations to sell the real ones
fwiw i went to seyberts site and looked at the packaging of the mooris
and to my eye they did not match the example on the left in the thread which reportedly is a real one
i have never tried one from them
