Review: Great Product to Help Organize! - Great product! An amazing tool to keep yourself organized, and everything digital.
Review: Lifelong customer now! - I was so excited to get this and rightly so! I love my rocketbook matrix! It does what it says it does! As a math educator, it's really helpful to work out all types of math exercises and then scan it into the cloud so I'm not having paper all over the place (I keep all of my math work lol). As an entrepreneur, I can also then use it for any other note-taking, brainstorming or writing I have to do, and either erase that or scan it. I really am stoked for this, and will probably now be able to stop hoarding notebooks and looseleaf! I just got the Panda Planner and am considering a mini notebook as well. A few notes: 1) It's a little tricky to use if you're left-handed though as the ink takes approx 15 sec to dry so will smudge until then 2) using the pen station, or adhesive pen holder, is super helpful as you can only use certain types of pens with rocketbooks and you don't want to lose it; 3) get a mini spray bottle that mists and has a cap or otherwise 'closes' so it's easier to wipe down (sometimes I spray the paper, and sometimes I spray the cloth if it's a small space that I need to erase) and won't accidentally spray in your bag; 4) the rubber/silicone tip is an eraser, so it's good for small and quick adjustments where you don't want to use the cloth, just be careful as you kind of have to wipe/rub the residue away in order to write over the spot again; 5) the frixion fineliner marker pens don't show up that well for me (may be the settings in the app), but it might be better to use the colored frixion gel ink pens instead of the marker pens if you use different colors in your work; 6) definitely get a separate set of the frixion pens with refills with this purchase as the ink in the pen provided really does go fast; 7) there isn't a bookmark or placeholder, so you might want to tie a thin piece of string or ribbon around the binding spirals to keep your place if that's important to you; 8) you might want to get a small supply bag to keep the spray bottle and cloth (and perhaps the pen(s)) together; and 9) I have found it helpful to use a clipboard to write on when not at my desk or table, as the rocketbook is durable but not super sturdy. I mean, you CAN use it without the clipboard w/o a problem, but if you prefer to write on a hard surface often, then a clipboard will help. Hope this is helpful!

## Questions & Answers

**Q: Does this come in executive size also?**
A: As of October 2020, no. It was just released in the first half of 2020 so it’s relatively new. Several customers have commented on their website requesting an executive size; so perhaps they will release one in the future.

**Q: Has anyone. tried to use a compass to do math problems? I am worried that a traditional compass will poke holes in the rocketbook.**
A: I've never tried it, but you are correct to suspect that a traditional compass "might" damage the surface of the Rocketbook.  If the damage is significant enough, the ink will settle into the small holes and won't wipe off.  However, as long as you are using Frixion Pens, heat would erase it.  

You could test it on one page to see if the surface is damaged, and if so, how much.   Even if there is damage, it might not affect what you are doing.  There are a couple of pages in the front that would be perfect for a test.  One test is worth a thousand opinions!

If you need to protect the surface, what I would do it to put a small piece of clear packing tape down where the compass point will go.  Packing tape is thicker, so as long as you don't press down too hard the compass point should not penetrate it.  You can still see the lines in the Rocketbook page to locate the point accurately.  

By the way, I'm a retired engineer, so I've done exactly what you are doing on a variety of vellums and drawing surfaces.  Never on my Rocketbook though!

**Q: Does this come with the spiral across the top?  A spiral on the side gets in the way in my opinion.**
A: The spiral is on the side/spine like a book.

**Q: Are there plain white pages included?  I need room to illustrate math problems without lines or grids in the background.**
A: one lined page, the rest are gridded.

### ⭐⭐⭐⭐⭐ The Smartest Buy I've Made on Amazon
*by B***S on July 8, 2025*

I buy a lot on Amazon, but this is hands down the best investment I've made. I used to spend almost $30 a month on notepads. Now, with this reusable binder, I can take notes, scan the pages into files, erase them with a damp cloth, and reuse the same binder again and again. The pens are universal too - I can use them in the binder or on regular paper. Simple, efficient, and it saves my company money every single month, which my supervisor appreciates.
