I'm a student and I find this whiteboard notebook extremely useful to jot down notes during class. I find it very convenient to use a white board marker as it can be erased of with the eraser provided, or simply, with your fingers! so no more ugly notes. You can keep your notes as long as you want; remove notes that you don't need anymore. It also can be used for great recreation too; that is the obvious, to doodle! you can doodle as much as you want, and the erase it if you don't like it!
I have been searching for this type of notebook for last few years, having in for the first time in early/ mid of 1980s! I wanted to buy this for my kids now, and am happy to have found these, not exact same design though.
