Kokuyo Campus Adapt Slim Binder - A4-30 Rings - Light Blue

The inside flaps are useful in holding loose sheets, I also use the A4 muji paper as this brand is much cheaper than kokuyo. The only thing is that the flap on the inside is not made well so after quite a few months of use, it has basically torn/ripped along the bottom edge.

Another excellent Kokuyo binder, with super high quality paper. It holds up and provides good protection when squeezed into my backpack with a heavy laptop and other notebooks. It lays flat when wide open and when folded inside out. I have added filler paper twice.

at first it looks expensive. but when I receive the product and using the product I did not think about the it selling price. Item is excellent quality. this is A4 binder with 30 holes. very useful if you put important documents. I am using this binder for my important printouts. currently making 30 holes manually with single hole puncher. I wish Amazon sells a solution for this 30 holes punching machine. Over all satisfied with the product.

very sturdy and practical. good quality.

Love the style of these binders! I’ve struggled so much with binders in the past. The three holed one always had pages falling out easily cause of rips when you weren’t careful. But not these! I haven’t had a single page fall out while using it for multiple semesters. It has also stayed in tact well. Really hasn’t gotten damaged at all and I’ve had it for about 2 years now! Love the unique look of the bindings as opposed to traditional ones. Although it’s thin it can hold a lot of pages also! I can’t get enough of this binder!
