Nasty, Dirty, Filthy! Deviant! Debased!
What kind of degenerate would add this filth to their work? And to make it so easy? True Grit should be cast into the flames of hell for encouraging this kind of defilement. The devil's greasy fingers are all over this wanton display of uncleanness! Satan's power only grows each time you use these brushes.
Do not use this brush set! Keep your files pure.
(I am only giving this five stars as an attention getting device. My real score is one inverted star)
