The pages are well organized, durable, and easy to write on without ink bleeding through. It held up throughout the semester and met all my lab requirements. If you need a reliable, standard lab notebook for school or research, this one gets the job done. ### ⭐⭐⭐⭐⭐ Perfect Notebook For Studies *by on Reviewed in the United States January 24, 2026* Arrived quickly, good condition over-all. Perfect for studying. The cover is plain but these are just research notebooks, you can bend the front flap comfortably and it is flexible. It's thicker and heavier than it looks but it has withstood some rough use already. ### ⭐⭐⭐⭐⭐ Best Lab notebook buy for a class! *by on Reviewed in the United States April 21, 2016* For $21 the is the Best Carbonless Copy/duplicate Lab Notebook on the market.Pros:-Water resistance fabric on binding, protects from water and chemical spills and manhandling.-Thick water resistance cardboard shell, with sticker on front to notate info.-First Page is a table of contents, again with fabric binding and a hard cardstock/cardboard page.-Perforated pages, which tear out easily. Yet, strong enough they haven't torn out on accident while writing in lab notebook.-Only Grid and page numbers on carbonless copy pages!-No additional tables, conversions so it can be used for my pre-lab quizzes!Cons:-The page divider in back was not perforated and difficult to ripe out for useage.(Infact, I didn't remove it for fear of ripping. Also the cardboard in the back of the notebook added to it's structural integrity. I used a laminated periodic table on cardboard that I used instead-no bleed through to other pages.)-No periodic table or extras in this lab notebook. I prefer it this way. Other might wish for more! ## Frequently Bought Together - National Laboratory Notebook, 4 x 4 Quad Ruling, 11" x 9.25", 100 Numbered Sets (43649) - 20 Pcs - Advanced Stainless Steel Biology Lab/Anatomy/Medical Student Dissection Kit Set - Scalper Knife Handle, Blades, Forceps, Scissors and Tweezers - 12 Instruments, 8 Blades - The Sheep Brain: A Photographic Series --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/2395310-national-laboratory-notebook-4-x-4-quad-ruling-11-x](https://www.desertcart.gr/products/2395310-national-laboratory-notebook-4-x-4-quad-ruling-11-x) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-08-15*
