KOKUYOCampus 2-Ring Loose Leaf Binder, A4, 2 Holes, Up to 100 Sheets, Light Blue, Japan Import (RU-PP158LB)

I use a Leitz hole punch (8cm spacing) to easily fill my B5 with US 8.5x11 paper. Of course the A4 notebook would work well with US paper too, but with the B5 notebook the US paper sticks out about half an inch on all three sides, giving you just enough notebook to protect your paper while providing a stripped-down footprint and a minimalist feel.Also these take acrylic paint well.

Really good-looking binder meets efficiency. That's basically what this binder is.The rings are durable despite being plastic and the opening and closing mechanism is also quite good.Overall, a great school product.

Not a bad notebook necessarily, but the B5 outer dimensions are pretty much the same size as an A4. With the big space for the rings, & the overhang on the other side you won't be saving any space with this, you'll just have smaller paper. The a4 flex binder feels more heavy duty than this one also.

I only received 3 of 5 tab dividers and they are hole punched twice. It fits my other b5 notebooks and paper. Cute color

Working product but a bad design. The binder doesn't lay flat which is annoying, the two rings make it hard to flip the pages and it gets stuck easily, the holes rip easily, and the mechanism to open and close the binder is hard to close (I'd prefer the type that's in a regular 3 ring binder). Good quality but I would 100% get a different product.

Muy lindo el cuaderno, le encanto a mi hija..

The product description mentions that it’s 5 pieces, also shown in the pictures. But it’s just 1 grey file. The quality of the file is good but 1100 for a single file is not a steal, even if it is Kokuyo.

Folder is okay but for the leaves you must have a very small font

way overpriced

整理するのに楽です。既存のふたつ穴のバインダーはリングの部分と表示の部分が弱いものが多く、この商品は表示がしっかりしているので使い勝手が良いです。

使いやすくて、便利です。
