I currently own three tote bags. Theyre all good quality, nicely designed, and I get compliments all the time. I gave them as gifts 💕

Such an awesome design and new twist on taking field notes, doodling, journaling etc. high quality paper and construction.

These are so fun! I could have bought less expensive gel markers but the packaging and colors are out of this world amazing!

Love these coffee mugs! I bought these specifically for their cultural significance and was even more happy with their size and how they fit in the hand. New favorite!

I gaze at it every morning, trying to memorize the cuneiform signs!

We love these glasses! We bought 2. Every time I pull one out of the cabinet, it makes me happy.

This is the second time I have ordered from this company. Both orders arrived quickly and packaged securly. Nice quality materials and craftsmanship. Looks exactly like the picture. I love it!

Everything I have purchased from Cognitive Surplus is top quality and beautifully designed. People always ask me where I got my math themed tote bag. I will continue to buy from this company. It is one of my favorites. First time i am in Oregon, I will stop in at their new shop.

These are real equations with captions, ranging from the Pythagorean Theorem to Schroedinger's equation. 430 ML of coffee and much to think about.

In general I LOVE the Cognitive surplus notebooks, I’ve been using them for years, all through grad school.

And this Nebulla version lived up to the hype! It’s so gorgeous!! I love the paper quality, I’m kind of a paper freak and the thickness and smell is just amazing. I never feel like the pages are going to rip easily. I tend to write kind of hard and with other notebooks, I’ve had my pen or pencil just rip straight through the page. Also, it absorbs my gel pens well so there’s no smudge. I’m left handed so smudging is always a risk, but not with the pages of these notebooks. I love the dot layout of the pages because it helps with drawing figures or graphs, and I can still write regular notes as well. I hope they come out with a Nebulla notebook that has the strap to keep the notebook open like some of their other notebooks have. But until then, I’m loving this notebook :)

Great product and great shipping

I love this so much! It's super great quality! I ordered it for my friend's birthday and she absolutely loved it!

Looks as advertised! Note that the glass is clear, black background in image is there for clarity.
