I presided the piano lesson and used it to write a staff line on a small whiteboard. The system is beautifully finished and satisfied. However, since I will uneven, I will think that I will purchase a large-size staff white board in this store soon.
I did not even know there are such tools on the whiteboard. It takes time, but as you can layout it freely, you will be able to clean up if you get used to it. However, I do not have to change it again and again.
