Good quality, exactly what my teen in Engineering 101 needed for class

Muy bueno para las clases de ingeniería

Good Quality - ***An Upgrade to consider for the manufacture is waterproof paper and cover

the lines used to form the grid on the pages, which is the bulk of the page - are drawn in very heavy lines and as such it is hard to use the paper in general. The grid should be drawn in "light" lines and not heavy lines since they are just a guideline for your drawings and not a main part of it. As it is, it is hard to use as the heavy lines are dominant on the page unless you draw with a sharpie or something thick lined. Please print the grid with light lines on the paper so the grid is almost invisible.
