WareLogging, MadeInFrance. Those orange-covered vaguely technical/engineering oriented notebooks. A wide range of sizes, GraphPaper, both WireBound and stapled varieties (maybe also stitched?)

<[Brennen]> I bought a $5 Bloc Rhodia N° 13 (double-loop binding, 80 sheets of graph paper at 4.1x5.8") on [February 14 2008], as a replacement for a larger work notebook that I kept forgetting to carry around. Seems pretty decent for the sort of object it is.
