It took only 2 years to research and test, however last week " GONE WITH THE STAIN" past the test. Removed ball point pen on the sweetspot, ball looks great with no markes or indents.
I have already checked with a top man who grades baseballs, he said, he could care less what is removed, as long as the signature he grades is real.
