Nasty flogger. This one HURTS. Can be cleaned with bleach. Only Alebeard would come up with this concept of a screen spline flogger. (Alebeard runs the Paintoy website, check it out.) Vicious and nasty with a comfortable rubber grip. Very Extreme. I'm not sure if screen spline is latex or plastic, but this is easily washable and disinfected.
Your bottom will be sorry.
