The lined sheets are perforated and can be easily separated out. The paper is light gray with white lines that do not further interfere with the writing and the written text are barely visible behind. It is very smooth and can be described well, whether in ink, pencil or felt-tip pen.
A beautiful and useful detail is the removable ruler of thin plastic, which can be clamped to the spiral binding. It can also be used as a bookmark. In the rear cover is still a pocket for loose notes or similar.
I like the block of the quality was very good and he makes a strong impression. However, the conventional black lines like me still better, which are clearly visible even in a slight decrease in light.
