Handsome journal
This journal has a very pleasing color scheme to it. The cover is colored a rich, deep auburn, with gold traces of geometric theorems embossed on it. The pages are smooth and much like the papers found in the other CS editions. It would have been better to put grid paper into this particular journal, since it has a mathematics theme; but otherwise I have enjoyed using it, and its aesthetic quality makes it a good buy. It looks even better in hand than it does in the photos.

Intriguing Look
There's something that appeals to the eye with the dark marbled red background and the different mathematical figures in lighter, warm lines. I wish I could have used this notebook as a kid. I think I would have liked math more.
Lovely!
