I received a sample of this product free from 3m to evaluate and I've got to tell you, sure of course this product would be great for the office, but if you have kids that love drawing on the walls with oh I don't know...permanent markers (like mine do of course), these are AMAZING!! The reason for only four stars you ask? I do love them really I do but as fast as my kids went through th em, they are quite pricey but I suppose when you weigh in the price of new paint and the time it takes to repaint it might just be worth it. Thanks 3m! [This review was collected as part of a promotion.]
