B. Toys Kokuyo Campus Adapt Slim Binder - A4 - 30 Rings - White by

I love my new binder. I grew up using these Japanese multi-hole binders and when I saw I could get one for my office I didn't hesitate. I love the transparent material and it's a very sturdy binder. Arrived from Japan well packaged and with a very nice note attached. Love it.

Nice and light, fits regular A4 paper and plastic sleeves from muji. Bought 4 items. Very cool looking opening mechanism

Amazing best binder ever. We’re flexible and nice to use

Bought this binder to fit 30 hole A4 paper from muji and it fit perfectly. It’s nice and easy to use. Good quality.

Ame la carpeta es súper funcional y justo como la esperaba

Me gustan mucho las encuadernaciones de 30 agujeros, más que de 4 o de 6 porque pasas las hojas como si fuera un libro o una libreta con espiral normal.Es cara así que, espero que me duren los materiales con el tiempo y los usos.Me ha gustado tanto que compré 3 unidades.

一般的に市販されていそうなバインダーです。百均で間に合わせようかとも思いましたが、なにせこの手の百均商品は材質が薄く、ペらぺらなものが多く価格相応なのでやめました。商品は本体の厚みも薄くはなく、安っぽさはありません。中の一枚ごとのファイルも厚みがあるので長持ちしそうです。

it made me question whether I should buy another one when I know I don't need it for anything. The rings are very easily opened and closed, and it's incredibly easy to rearrange papers in the binder. It's also a super good size to substitute a notebook for since it's a thin binder and is flexible so it's not bulky. The pockets on the inside are just a bonus!Also, I never write reviews so the fact that I made a review for this product means you know it's good.
