Looks similar to this, wonder what the condition is called.
Anyone hazard a guess what would come out if you cut one of them open?
Their pimple things.
For some reason poping pimples on your sack is not a good idea.
I have them, but not to that extent.
Just cut the open and remove the gunk.
Also the are solid as fuck, the skin around them is relatively strong makeing the gunk more compressed.
