Kokuyo Campus Smart Ring Binders 3 Pack, B5 Notebook Binder +100 Sheet Refiller Paper, 25 Sheet Capacity, 26 Rings, Lemon Mix, Perfect for Work, Study & Journal, Japan Import

Not sure they’re worth the hype, but you can’t have too many pages in them and the binding ring is a little flimsy. It’s a cute concept, and maybe I’m doing something wrong. But I’d like more than a couple pages in a notebook

I enjoy these because if I want to I can leave them at home and just carry some of the paper in a binder on its own. The only thing that is a hassle is opening it. Other than that, looooove them

Very nice mini binders--easy to tote around, nice for small reports/study notes. Only issue I've had is the spine opening up when placed in a bag and the tab catching on another folder. A locking mechanism (I believe the 60 page version has one?) would be good for security. I've started transporting them in an A4 or B5 bag meant for carrying notebooks, like Lihit Lab.

Really enjoy using these notebooks. Makes it easier to carry all my work, without feeling weighed down. My only complaint is that sometimes the binder pops open. I’d recommend working with them while they lay flat.
