Keep my work notes tidy
Excellent product. Very handy. Keep me organised instead of scraps of paper lying everywhere.

Great quality and value for money
Sturdy and well designed and made A5 cover for spiral bound books. It came with a 50 sheet blank book, but my 200 sheet spiral book fits perfectly. Also lots of extra spaces for business cards and loose A5 pages. The ribbon for remembering the last page used is useful. I like the mix of fabric and "leather" on the cover.

not sure what I will use if for bit well made product
This arrived in good time from Japan.. I'm not sure if I'm honest it was what I expected or indeed if I'll use it, but it might be one of those things that one day I'll suddenly realise why i kept it

Fantastic Organiser!!!!!!!
I really love this! It's even better than I hoped it would be. I really needed a way of pulling together all my notes, lists, post-its, diary etc. instead of carrying loads of stuff around with me and losing bits. This is perfect! I have a notebook/to do pad and post-it pad in mine as well as pockets I use for loose papers and it fits my A5 week to view diary too. It's unusual, I've never seen anything like it, the Japanese have it spot-on. You can customise how you use it and what you put in, I'm buying another for personal use too as the A5 size will fit my handbag. Quite a few colleagues have asked me where I got it.

Ok, but not really A5 sized
Interesting and functional cover but too big to be A5.

Great cover for my planner
I got this to put my Hobonichi Cousin in and it’s a perfect fit, it has a great amount of space for 2 additional A5 Hobonichi memo pads and there’s still room for another if I need it. The notebook it comes with has gel pen and fountain pen friendly paper so that’s a nice bonus. I’ll definitely be buying another for my A5 Stalogy 😀

Best notebook cover ever!
I love this. I got my Leuchtturm 1917 in one side and the other side comes with a small ring bound notebook in it. These both fold out to reveal an inside with three business card sized pockets and a larger A5 sized pocket behind them. There are three ribbon placemarks, a pen holder and a thick elastic strap to keep everything together. I got the navy blue which is lovely. The texture of the fabric is nice to touch. Japanese elegance, worth every penny.

The paper in the notebook is of fairly good quality
Well made item but with very little leather hence the 4 star rating, I use it as a daily diary and notebook.

This is singlehandedly my favorite stationery purchase of all time, and as an obsessive pen stickler and someone with strong opinions about the distance between ruled lines, that's saying something. As with many Japanese products, this is incredibly well thought out. The build quality is sturdy and flexible, feeling like it'll flex with life's demands while holding up for a long time through the abuse of day to day. There are 3 places to hold notebooks, allowing for max versatility and capacity. The pocket on the front allows for carrying extra pens and goodies which is really nice when I'm doing my zen set up time with highlighters and tabs and different pens, but I don't keep things in there on the daily as the lumps on the front would impact writing on the left sheet of my planner. The only thing that would make this more perfect is if it had an additional elastic band on the front cover, so I can open the planner up to the current page right away rather than using the ribbon, but that's easily fixed with an aftermarket notebook band. The workflow of a planner/notebook blend is ideal for me. This thing is amazing in meetings. I have my calendars, my week view, my to do list at hand with room and options to flip everything around to have a blank page open on either side of my spiral notebook. That feature is honestly the best thing about all of this. I can also flip the notebook out to use in tandem with the planner or remove it entirely. I've gone through literally hundreds of planners and notebook combinations, zero exaggeration. This combo is absolutely ideal for me and as someone battling ADHD and the dopamine spikes and valleys that come with it, I'm months into this thing and it's still working for me. It feels natural. Those who know that feeling, know what that means. Yes it's just a notebook cover but for those familiar with the struggle of finding something that WORKS in a world not built with you in mind, each piece of that equation matters. I'm ride or die for Kokuyo products, and this one is honestly one of their finest creations.

必要な機能は全部揃っていて、なおかつスリムなデザイン。 プラスチックの仕切りが芯になるので手持ちのままでも書きやすい。不意な会議でA4資料もらっても、二つ折りにしてポケットに挿すなり挟めばちょうど収まるので持ち歩きもラク。ゴムバンドのおかげで中身が脱落したり不意に開く心配もなし。ビジネス用途に耐えるデザイン。 付箋とか入れられるようにフタ付きポケットがあるとなお良かったのですが、これ以上を望むとカバーが肥大化すると思うので、絶妙なバランスかもしれないですね。

Es una funda con varios bolsillos. Viene con un cuaderno de la marca. Se puede usar con cualquier cuaderno A5 pero si lleva espiral puede que la funda quede muy tirante.

This folio is great and versatile. I can fit a couple notebooks and it even comes with one! The price was right when I ordered it, great for journaling or every day carry

L'ho acquistato per tenere 3 quaderni degli appunti che uso in facoltà, perfetto! Si tolgono e mettono con facilità ma sono belli fermi una volta che li metto, io approfitto della taschina per piccoli oggetti o le penne. Un tutto in uno che permette di essere sempre pronti anche in movimento
