Kokuyo Inspiracion Perforated Page Twin Ring Notebook - Semi B5 (7" X 9.8") - 5 mm Graph - 50 Sheets - Black

perfect, no-frills graph notebook at a decent price with coopon!
great paper, graph ruled lines are not too dark, hard back cover supports so you don't need a desk.
I know Inspiracion is like a maybe-ripoff of Inspiration (maruman) but I got both Inspira---whatever notebooks and I kind of like this one better because the graph is on the front AND the back of each page. I prefer it that way, but "to each his own."

This is a real nice and well made notebook. Pages are smooth, creamy and crisp - excellent for a gel ink pen.

This will fit nicely with my Nomadic A4 Shoulder Bag.
