This is nice because I can move it from one notebook to another as needed and it is easy to insert my Pigma Micron pen. The disk loop style I've been using was nearly impossible to get the blunt Micron into.
Another nice thing is this lays flat when the pen is removed so the notebook can lay flat as well.
I would recommend it to a friend.
