Review: WORTH THE PRICE - The cover is nice, the paper is thick and sturdy. Gel pens and markers don’t bleed through the paper. It works! Spilled hexane on this bad boy and it smelled a little (nothing esters can’t fix lol). The cover has also held up with highly concentrated sulfuric acid so yay! It has plenty of pages so this lab book is coming with me to Ochem 2. 5/5 recommend.
Review: Favorite notebook!! - This is an awesome notebook, especially for graduate students working on research. I use it every day to record my research progress and thoughts. The pages are thick and great for writing, and I really like the large size and hardcover binding. I only wish they had notebooks with more (e.g. 200) pages!

### ⭐⭐⭐⭐⭐ WORTH THE PRICE
*by Z***A on January 14, 2020*

### ⭐⭐⭐⭐⭐ Favorite notebook!!
*by C***A on August 17, 2018*

This is an awesome notebook, especially for graduate students working on research. I use it every day to record my research progress and thoughts. The pages are thick and great for writing, and I really like the large size and hardcover binding. I only wish they had notebooks with more (e.g. 200) pages!

### ⭐⭐⭐⭐⭐ Exactly what you want (even with one tiny flaw)
*by R***S on April 22, 2018*

Exactly what I wanted. Great quality paper that ink doesn't bleed through. The only complaint I have (and it's minor) is that there is no exterior labeling or identification of this as a lab notebook, but I suppose you could always have that added using a label or with an external bindery service.
