Very good buy 82

Well-designed notebook. Large format, heavy paper, plastic cover. The choice of spiral binding is discussed, there are advantages and disadvantages.
The lignure really helps my son. This is much more meaningful to him, and fun when told "F rises to the sky then down to burn the ass" instead of "you go up to that line there and then you go down to that one."
The presence of the line of friendship is more: it makes an implicit visible.
In conclusion he loves his notebook and makes his exercises with pleasure. Only regret in the product description we did not help choosing the size of the lineage that suits our child. I found the back of the book I should have my bearings instead to 3 mm. So this will be my next purchase.
