I don't know if this is Normal therefore i thought i should ask. I got 2, 3 head hammers from David a while back and now its up to 10 heads but on 2 of the heads its as if the dead center of them have a Huge clear bubble in the middle. I noticed today that its actually part of the polyp. Is this Normal? If so why is it doing it, and if its not what can i do? Thanks for all you input and Help.
