Also, when I look at the prices on amazon.se it looks like they cost around 5-10c each, a bit hefty for a student.
Another note, it was actually surprisingly difficult even to get a hold of blank paper notepads in Sweden in the 90s. At least cheap enough. The cheap ones were all lines or squares.
Even today for students constrained financially, they can print out a dot grid on blank printer paper, perhaps in a faint blue or grey to recreate the effect.
You get a nice mix of benefits of blank paper and graph paper.
