Very pleased with this product - it's like a giant post-it note!!! . Didn't leave any residue or marks on our walls. Only issue was that the backing (cardboard) was not strong enough to support the pad, it would not stand up on it's own or remain flat - so I suggest to either set it up on an easel - if you have one, or leave in the box otherwise the pad will crumple.
