Kokuyo Campus Smart Ring Binder, Up to 25 Sheets, B5, 26 Holes (Clear, Light Blue, Light Pink & 100 Sheets Paper Set)

What a great little binder. The push-button opening on the rings is very clever and easy to operate. (Illustrated instructions on the back.) Forget the lethal metallic spring action and nipped fingers of the average British ring binder. It's a nice slim alternative to large-size rings – you could stash several in your bag – but it still manages to hold a lot of sheets. The paper is typically excellent Japanese quality, too, fountain pen friendly, and although this review isn't about the paper, you do get a few sheets included with it.This B5 format is for 26-hole paper, which is widely available in Japan but not in the UK, so you'll need to buy it (also available on Amazon) or invest in a Carl 26-hole punch to make your own. It's worth it because the extra holes means paper stays put. (And you can insert mini note sheets like the ones Maruman makes.)For just over a fiver and free shipping, this file is astonishing value. Time will tell if it stands up to rough handling, but my other Kokuyo products have proved to be pretty robust, so I expect this to be of the same build quality. Like most Japanese stationery, it's thoughtfully designed and a joy to use. The service was good too.

A really handy, slim and lightweight folder.Be aware that the paper inside is JIS B5 (Japanese industrial standard) rather than ISO B5 (international standard)

It is a good quality item but comes smaller than shown and is only A5 and a little overpriced

This binder is just the right size. I had heard that b5 was a better size than a5 and a4 for the writing experience and it is. Bigger than a5, so you can get more words per page, but not as daunting as a4. I use this item to hold my current writing, as it only holds 25 sheets of paper, then transfer it to a bigger folder when i have completed it. At first I thought it was a bit expensive but the design is well thought out and the binding spine is lovely to use, so it's well worth the cost. It is sturdy enough to transport in my work bag and I have had no problems with it.

The media could not be loaded. The quality is amazing and the price is so good too considering it’s for 3 binders and a stack of paper; if you buy just the notebook u gotta buy like stacks of loose kokuyo paper it’s on Amazon too overall it’s perfect for school especially for GCSEs or six form

Very useful and refillable very aesthetic love it

For the price, I wouldn't say they were amazing, they feel very delicate and flimsy. They come with small amounts of paper which is unique to the binder, so you'd have to pay more on top for paper refills. However, it is very cute, the binder is a great tool when removing paper and writing notes with ease.

They were a little tricky for me to open at first, but once I figured it out I had no problems. The paper is great as well, I love the dots on the lines to make is easier to use with - for example - math notes. The dots are small enough to not bother me when I'm writing, but large enough to easily use when solving math problems.
