I received the Post It Easel Pad free from 3M for an evaluation. I received this product at home and it was put to use right away as we organized our home office. 1 sheet was put up on the freshly painted textured wall and stayed there for over a week before we took it down and adhered it to a wooden door. We used both a Sharpie marker and a regular pen and both worked just fine on the paper. I then took the pad to the school I volunteer at and the kids stuck it on the carpeted wall and drew on it with crayons and finger paints. Nothing bled through the paper. They took the sheet down and moved it around several times and it still adhered to the wall. Lastly I took it to work and during a meeting we stuck it up to the White board and it adhered to that surface just fine. I will definitely use this product again!
