### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Great for College!
  

*by T***K on Reviewed in the United States 🇺🇸 on January 9, 2013*

This is a great lab notebook if you don't need the carbon copies! I wouldn't really consider the paper heavyweight though. It felt a lot more like medium weight. With that little detail aside though, I love love this notebook for my labs! I purchased it originally for my Organic Chemistry class, and it has now become my go to for lab notebooks! Love love the fact that its 8.5 x 11 and hard covered! Helps prevent the paper from getting wrinkled in my backpack! My only concern is that the price seems to be going up on this notebook :/ even at 7.99 I thought it was a tad expensive. Now its over 10. I docked it a star for the price.

    Sturdy lab notebook
  

*by P***S on Reviewed in the United States 🇺🇸 on September 14, 2013*

The quality of the paper in this book is quite good. I use a ballpoint pen with it, but could easily use a fountain pen without worry about ink spread. The one thing that's important to me and that's missing is page numbers! In fact, I would have liked a footer on each page with the pre-printed page number, a space for the signatures of the author and reviewer and the date the lab notes on that page were reviewed.

*by C***N on Reviewed in the United States 🇺🇸 on September 1, 2016*

It's a simple, practical lab notebook if you want a cheap one. It's pretty well made and should hold up for a few semesters. The pages are just plain graph paper, no header or footer lines, no page numbers, so be prepared for that. Sharpie markers bleed through the page, ballpoint pen doesn't.
