Review: EXCELLENT paper, useful for more than just engineers! - *** BACKGROUND *** I teach math review classes for nursing students (I myself am in nursing school.) I needed to find a clear and professional way to "show my work" in my own handwriting to give students in my quiz review packets. I didn't want the typical graph paper since after photocopying it, it was very difficult to read as the grids were sold dark, blending in with the numbers I was writing. I didn't want the typical college ruled notepaper as again, the lines were interfering with showing my work for a problem because of the very pronounced lines during photocopying. After much research, I stumbled across this product and after reading what others had to say, both here and elsewhere on the web, I felt this was the best choice and it has proven to be just that, I immediately ordered one pad and had it over-nighted as I needed it the next day to do my lesson plan and quiz review packets. I then ordered another two with the free two-day shipping option. I was pretty annoyed when they both arrived the same day since I essentially spent $3.99 on shipping for no reason, but regardless, I had the paper and began using it. *** EXPERIENCE IN USING THE PRODUCT *** I was impressed right from the beginning. The graph paper on the back just slightly shows through on the front making it easy to keep your work professionally aligned, without showing up on photocopies or scans. The borders around the edges are nice so I can leave comments on the student's work, have a spot for them to leave their name, class name, date, and so forth, As others have said, the paper is green, it's on the thinner side (as you would expect from engineering paper... it has to be in order for the grid on the back side to show through on the front.) It works AMAZING for my purposes and I am not an engineer. *** CONCLUSION *** The lesson I learned here and what I hope you take away from this is, this pad is obviously excellent for engineers, especially when compared to the cheap Ampad brand which apparently has uneven graph lines and is generally inferior to this product. More importantly is that this paper has so many more uses than for engineers only. Math and science teachers, medical and nursing school students, and many others can benefit from what this paper offers. Somebody complained that the tablet is too thick at 200 sheets and is hard to write on. I agree, but as someone else mentioned, there is a very simple solution: separate the pad into two 100-page tabs and use one at a time... problem solved. I tear off individual sheets as I use them so this isn't and won't be an issue for me or many others. If that solution doesn't work for you, feel free to order the 100-sheet version but you'll pay more per sheet doing it that way. *** I hope this review was in some way helpful to you... if it was, please let me know! I would really appreciate it lets me know that I'm at least helping a few people make an informed decision before purchasing! *** Review: My review as an engineering paper first timer. - As a junior engineering student at Missouri Science and Technology, I can attest to the quality of this paper. Before I used this paper, I used either notebook paper or blank printer paper to do my homework. The notebook paper drove me crazy because I wouldn't be able to concentrate if my calculations were too large to fit on one line, but the printer paper didn't provide any structure for my writing so my calculations would gradually curve down to the right as I wrote from left to right. While I know that there are people much better with their writing discipline, but this paper really has helped me. The green is really easy on the eye and provides great contrast. The grid lines are hard to explain. They're visible when you need them and look for them but they fade into the subconscious when you aren't looking for them. Kind of confusing, but that's the best way I can explain it. I've never used any other brand since I just started to use engineering paper, but I don't think I have any need to try another brand. I use .5mm and .3mm and neither poke through. The paper erases nicely as well. I bought 4, 200 sheet, packs and just tore them in half so I'm not carrying a massive stack of them. Haven't run into any problems listed by other buyers such as misprinting, innacurrate cuts, and etc. I was kind of worried buying so many, but the risk was well worth it. I'm writing this review for the other students out there like me who want an in depth first timer review of this product. Thanks for your time, and I hope this helps you come to a decision. ## Features - Computation paper - One side quad-ruled, one side plain - Green Eye-Ease paper to help avoid eye strain - 100 Sheets/200 Pages - 5 x 5 quad ruling, 5 squares to an inch ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0007LTJO0 | | Best Sellers Rank | #29,047 in Office Products ( See Top 100 in Office Products ) #12 in Computation & Data Pads | | Binding | Office Product | | Brand | National | | Brand Name | National | | Color | Green | | Customer Reviews | 4.6 out of 5 stars 907 Reviews | | Global Trade Identification Number | 00073333423822 | | Item Weight | 12.8 ounces | | Manufacturer | REDIFORM OFFICE PRODUCTS | | Number of Items | 1 | | Number of Sections | 1 | | Paper Size | Letter 8.5 x 11" | | Ruling Type | Squared | | Sheet Size | Letter 8.5 x 11" | | Special Feature | Soft Cover | | Style | 100 Sheets, Green Paper | | Theme | Book | | UPC | 635665095605 809099125867 073333423822 787463809813 | | Unit Count | 1 Count | ## Product Details - **Brand:** National Hardware - **Color:** Green - **Theme:** Book - **Sheet Size:** Letter 8.5 x 11" - **Pages:** 100 Pages - **Style:** 100 Sheets, Green Paper - **Ruling Type:** Squared - **Special Feature:** Soft Cover - **Number of Items:** 1 - **Specific Uses For Product:** Note Taking, Record Keeping, School, Office, Home Use ## Images ![National Computation Pad, 5 x 5 Quad Ruling and Unruled, 8.5" x 11", 100 Sheets (42382) - Image 1](https://m.media-amazon.com/images/I/61ARRXHXvaL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ EXCELLENT paper, useful for more than just engineers! *by B***P on November 27, 2014* *** BACKGROUND *** I teach math review classes for nursing students (I myself am in nursing school.)

Before I used this paper, I used either notebook paper or blank printer paper to do my homework. The notebook paper drove me crazy because I wouldn't be able to concentrate if my calculations were too large to fit on one line, but the printer paper didn't provide any structure for my writing so my calculations would gradually curve down to the right as I wrote from left to right.

Thanks for your time, and I hope this helps you come to a decision. ### ⭐⭐⭐⭐⭐ I am just picky about paper so I ordered three brands, *by F***Z on September 17, 2016* Tops, National, and Ampad, and I did my own comparison. Tops has the sharpest lines, then National, and Ampad respectively. Thickness of sheets was very close with National being the thickest, 7 percent thicker than Tops and 9 percent thicker than Ampad. As you might suppose, it is more difficult to see the grid lines through the paper of the National than the other two, however all brands have grid lines visible through the paper. National is slightly darker green then the other two where the color between the other two is almost indistinguishable. The most important thing is the look and feel of the paper and smoothness of the writing and I tried to be as objective as possible but it really comes down to preference. National feels the smoothest with a sharp .03mm mechanical pencil, very close behind is Tops, and Ampad is noticeably worse in a side by side comparison. National again wins in the look and feel being more uniform and flat compared to the slight waviness of the other two, and less likely to buckle when erasing. Lastly, at the time of purchase Tops was $6.14 for 100 sheets, Ampad was $5.81 for 100 sheets, and National was 3.99 for 100 sheets all prices were as add on items where the total order must be $25 or more. Price aside, I think it's pretty clear that National comes out on top of the other two brands unless not having the grid lines show through as well is just a deal breaker. Tops is also very good and is worth paying a few cents more for than Ampad. ## Frequently Bought Together - National Computation Pad, 5 x 5 Quad Ruling and Unruled, 8.5" x 11", 100 Sheets (42382) - National Computation Pad, 5 x 5 Quad Ruling and Unruled, 8.5" x 11", 200 Sheets (42389), Green - TOPS Engineering Computation Pad, 8-1/2" x 11", Glue Top, 5 x 5 Graph Rule on Back, Green Tint Paper, 3-Hole Punched, 100 Sheets (35500) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pe/products/4671107-national-computation-pad-5-x-5-quad-ruling-and-unruled](https://www.desertcart.pe/products/4671107-national-computation-pad-5-x-5-quad-ruling-and-unruled) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-09-13*
