I am a notebook and pen junkie. I love them and carry multiple of them everyday for a variety of uses. The notebook itself is of run of the mill quality. Graph paper on the inside lends itself to all sorts of uses and that’s a plus. The inside covers have two rulers, inches on the inside front, metric on the inside rear. These notebooks differ slightly in dimensions from other popular brands. This will cause fit issues in some tighter covers, if you use a cover. Overall, good, but not great notebooks.
