Better quality than I thought
This was my first CS purchase, and due to the slightly janky nature of the website, I wasn't quite sure if I would paying good money for an equally good product. But the notebook feels really solid, the paper is supple, and I think I got my money's worth. The website could stand a little UX renovation, though.

Amazing!
This journal is amazing! The pages are thick and very quality. The colors and illustration look even better in person and the texture of the cover is super nice. Cognitive surplus definitely secured a customer for life!
