Sol: Spectra Hardcover Notebook - Lined/Grid
This notebook celebrates the sun and its electromagnetic emissions that power all life on earth. Use it to catalog your adventures on one trip around our star, take notes in physics lecture, or record data in the lab.
The textured covers of these notebooks have the feel of old textbooks, and with advanced lay-flat pages, they want to fall open, like a well-loved library book. Go ahead and see for yourself – these are the notebooks your most brilliant ideas have been waiting for.
The Hypothesis series is built with high-quality 100% recycled paper and printed with soy inks, leaving a light footprint. Be inspired to ask the right questions, connect the dots (even when they’re really far apart), and keep pushing humanity forward, so that tomorrow is always brighter than today.

Frequently Asked Questions
Love the notebook, really enjoy having half grid and half lined. Perfect size, good page thickness for my gel pilot pens. Adore!
“One of the most thoughtful presents”
I gave this to my aerospace engineer friend as a birthday present and he loved it! I didn’t get to test it, but it seemed like good quality paper. The graph paper looked good too.
Wonderful notebook, terrible timing
This notebook is beautiful! I purchased it for my job working in a planetarium. Unfortunately, it arrived the day after I got furloughed. So I haven't used it yet, but I can tell it's very high quality.
