First these are not really washable markers. They say on the packkage that they will not wash off walls or clothing. They will only wash off whiteboards or other similiar 'washable' surfaces and skin. But worse than that is the crayons just fall apart. When you try to sharpen them they just crumble. If you peel back the paper, they just fall apart. And the colors do not show up well on the included board. This is a really bad product.
