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 amazon. 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.

So pink so pretty
Pretty and light so you can squeeze in around 25-35 sheets of paper in between.

Good purchase!!
I Personally loved the notebook I think it is perfect in size and very convenient. I put index cards on the notebook (hole punched them). Though it’s more efficient to buy a 26 ring hole puncher and the paper which can be inconvenient but it’s worth it. The notebooks are very light weight and best for highschool and college students who don’t want to carry heavy weight. The paper capacity is pretty high as well I’ve been using them for around a week and take many notes and only have used 4 pages in total thought I think the spirals can my a little sensitive as long as your responsible you will be fine. Overall it was a very good purchase and came fast!!

It’s good<3
i liked it it’s very convenient! the only thing is it comes with a bit of sheets so you’ll have to buy more paper separately. Luckily i had some from my last Campus Binder so it wasn’t much a problem. so slim n nice <3

I Love It!
I like the compact size and the feel of the sample pages. I did order refills as well. It is a bit tricky to open at first but with practice it will be easy to refill.

Love this
This is a great school notebook option for those that like to swap out pages, rewrite and reorganize their notes. The spiral binder part is a little finicky to open and close and seems very delicate, like if I push to hard or the wrong way, it would snap, but overall I like the option and reusability of this way more than anything else I've tried. I've heard that Muji has a similar style, so would like to try that one out too.

I received the product good but the packaging was horrible what if it broke the binder? Or left some crease mark?? It was kept inside a square rectangular box and the binder was folded and kept it in tightly.

Serves exactly as the stated purpose. However for me personally I thought that writing on B5 paper was really small, so therefore demotivated me into writing notes. It was okay and they provided 10 pages so I had to buy the rest myself. I was really hyped about this product before getting it but now it just lays on my shelf untouched. Quite expensive so I would use my money elsewhere like on spiral books instead of binders.
