These Oxford School course blocks have a sturdy cover so that they remain beautiful for a long time. The Optik paper is extra white, extra smooth and prevents printing. The 5mm diamond pages are ideal for writing down numbers and calculations. The tear-off sheets are easy to store in a binder. The blocks are glued on the left side. In addition, the course blocks can be used in combination with the free SCRIBZEE app to scan and save notes.
