I received this as a free trial from 3M, so I put it to the test, my kids. Ages 7 and 10, they stuck these to the walls and got out their markers. Excellent as far as staying put! They've been up a week now, and I tested pulling one down -- easy release, no marks on the wall. Even better, the prolific use of markers did not bleed through and mark the wall either. Thumbs up! Pretty sure this can stand up in the board room, since it handled the play room. They also make great impromptu movie screens for our projector! [This review was collected as part of a promotion.]
