## Description

desertcart.com : Kokuyo Campus Smart Ring Binder, B5 Light Pink Refillable Binder Notebook 26 Holes with 10 Extra Loose-Leaf Paper, Up to 25 Filler Papers for Work & Study, Japan Import (RU-SP700LP) : Round Ring Binders : Office Products

Review: Portal and cute binder! - INSTRUCTIONS: First off, it has a lock to protect the binder. To take off the lock, place your finger through the bottom hole of the lock and push it out to the left. If you get stuck here, grab onto the bottom tabs on the side and pull those out. Next hold the lock and pull it up. To open the binder rings, press the plastic button on the top. Make sure you don’t block the bottom part of the spine or else it won’t open. To close the binder, you pinch the rings together. It’s a very slim and portable binder with a nice pink pastel color. It’s best paired with Kokuyo campus paper which can also be found on desertcart. The maximum amount of pages it can hold is 25 but I was able to squeeze in 40. Though if you overload the binder too much it will have a difficult time closing and your pages will easily fall out. I wouldn’t suggest being rough with this binder. It holds pretty well, but also feels fragile if handled carelessly. The paper is very silky and high quality. It feels smooth to run pen ink over it. Unfortunately, b5 plastic sheet protectors will stick out. I’ve used maruman clear pockets, so the kokuyo campus clear pockets /may/ fit better. This binder seems to be best for holding paper and not plastic sheet protectors. Overall, the Kokuyo brand is very high quality as most Japanese stationery products are. This binder is a great way to save buying multiple notebooks. It’s easily refillable and portable to carry around. If you want a binder that is a little more studier and can hold more pages, I would get the 60 page version of this binder, which is a lot thicker and more sturdy.
Review: So pink so pretty - Pretty and light so you can squeeze in around 25-35 sheets of paper in between.

## Questions & Answers

**Q: does it come with paper?**
A: Yes, but it only comes with a few sheets. You may want to buy the B5 paper with 26 holes sold on Amazon, or buy your own offline. 
I got my extra refills from Muji.

**Q: can this fit a year's worth of paper?? meaning a year's worth for one class**
A: no, the thicker it gets the harder it is to maintain

**Q: Is the plastic hard? or is like the five stars journals where its plastic but still bendable??**
A: Yes, the plastic is hard but is bendable.  Nevertheless the plastic is pretty sturdy and will not bend so easily, keeping the paper inside undamaged.

**Q: are the pages perforated?**
A: No, they aren’t perforated. But there’s no need. Just open the binder and take the sheet out. It’s that simple and that’s the point. Use a cut by ruler if you need the binder holes off. Easy. Just cut all pages at once and totally even. Here’s a link to 5-7mm refills:

7mm rule refills for the binders (I use these. More room to edit my writing):

They have soft ring binders that’s arent refillable and normal notebooks too. Look up Campus by Kokuyo. I’m an author and mangaka and use these papers extensively for note take. They don’t bleed with foundation pens either. 

On to of that they’re liked but also graphed with light but visible dots. There’s so much you can do with these. 

I used these in school as a kid in Japan.

### ⭐⭐⭐⭐⭐ Great design, durable, reusable
*by M***E on August 20, 2018*

Very satisfied with product. The kokuyo binder series are one of my favorite notebooks to use. After months of daily usage, the rings have not become loose. After yearly purchasing and throwing away of ordinary notebooks I never once finished using, this notebook saves paper, and light to carry around. Good quality. Definitely recommend purchasing.
