Journal science
This is a gift but relative liked the one previously purchased and wanted another one for Christmas

Great gift
It is so beautiful! I bought it for my sister but I might need one for myself.

We haven't spoiled the oceans completely, this notebook makes me happy
I LOVE their products, sturdy, beautifully and imaginatively designed and made, great customer service and they employ the differently-abled. I purchased: 5 hardcover notebooks, 2 softcover notebooks, a mega-mug (works for soup as well as giant coffee), and 3 of the cards. I am delighted with everything and have pointed several scientist friends to the site.

Love it but...
I love this journal! It’s the perfect size to use for bullet journaling and the cover is absolutely beautiful! The reason I didn’t give the full stars is because the color is full compared to the picture online as well as the cover all ready started showing wear after the first month. I only use this journal at work and was incredibly surprised by how quickly the corners and edges were worn down. Would recommend this to a friend but be wary about how it holds up.

Gorgeous Notebook!
This is my third Cognitive Science notebook this year, and fourth overall. I love the beautiful design of the cover, it brings me just joy just looking at it! I also really enjoy the dot grid paper on the inside, it's great for making graphs, charts, and writing notes! As you can see from the pictures the ink (of the pen I use) doesn't really bleed through to the other side of the paper, which is great for me because I always use notebooks front and back. The only reason I did not give this notebook 5 starts is because the cover did start to fray at the edges. The cover here is a different material than some other Cognitive Science notebooks I have had in the past so maybe that's the reason why. Also I the notebook might look this way because I am definitely not nice to it. I work full time in a lab and it's constantly being used to carry flasks, accidentally sprayed with ethanol, and other lab mishaps. Overall it's a fantastic notebook and I look forward to my next Cognitive Science notebook!
