why wont they be available to the public?
Well generally the pro issue gloves in sausage finger aren't available to the public. Kook make many for pros but won't release them as "they won't sell"
Gunn and Moore do a pro range of softs the won't sell as
@Edward Lowy of GM has said "they won't sell"
And as for the Pumas, pun and pro direct tweeted that they won't be available to the public, there just a marketing gimmick to get people talking about the tricks range, which is a toned down version of said gloves.
As we can see from above bough, the mcullum glvoes(which he no longer wears) are actually available in India.
Now I just need to find someone will to import.
