Review: Best and thick quality papers - Perfect item for high school kids. Quality of pages are excellent.Doesn't rip by multiple page turn
Review: The best notebook for engineers. Ever. - I started using these back in the late '90's (*gasp*) when I was an undergraduate. I have at least 20 of them on my shelf - each from a different class - and I still refer to them from time to time. They have held up exceedingly well. Now that I'm doing my grad work, I'm glad to see they're still available. I just bought a dozen of them, to use for school and for other projects. They are perfect for engineering, math or science notes and projects. The pages are larger than 8.5x11, so you can easily staple or glue handouts into them. The front and back cover are sturdy and tough, and the binding is strong but flexible. The 1/4" grid spacing is great for drawing schematics or charts or graphs or whatever you need to do. Good quality paper too. I have a few Ampad computation books too, which I bought when I couldn't find these, and they (the Ampads) are inferior. The paper is rough and pulpy, and the spine _much_ too stiff -- it won't lie flat on the table. One of the nice things about the Nationals (used to be called Avery, but still #43648) is that you can "crack" the spine and the book will lay flat. If you're an engineering student, this is the book you want to buy.
