No graffiti on OUR back side, it's a double-sided blank dry erase board. Our Dry Erase Surface will not Permanently Stain or Peel Off. We guarantee our markers to write up to twice as long as the standard "teacher sized" markers. (Just put the cap back on after use.) Our erasers are guaranteed indestructible. (Go ahead - try to pull them apart!) We know you will agree our marker tip is almost indestructible too!
