This Maruman Loose Leaf Mini Paper are like index cards for your binder. The small sheets of paper fit into most A4, B5, and A5 size binders, and are a great way to keep detailed notes in a smaller space.
Paper dimensions: 3.4 x 5.0 inches (8.6 x 12.8 cm).
I use these as additional note cards in my Kokuyo Campus Smart Ring Binder. I
can fit two high, meaning one at the top of the binder and one at the bottom of
the binder, or alternate placement of them so I can have additional notes where
I want them.
The paper is smooth, but doesn't seem as smooth as the Kokuyo Campus Loose Leaf
Paper - Sarasara A5 that it sits in my Smart Ring Binder with, but only
marginally less smooth in my opinion.
This was very much worth the purchase and serves me well.
