Q&A

How does a multi-hole slide binder mechanism function?

To open the binder, locate the slider tab at the base of the spine. Simply slide the tab horizontally or press it gently to open the rings. Place your standard loose-leaf sheets onto the rings, then pinch the rings closed. The locking slider secures them tightly to prevent sheets from shifting during daily use.

What is the benefit of using 70gsm Japanese fountain pen friendly paper?

Japanese 70gsm paper is engineered with highly compacted fibers and specialized surface sizing. This structural density prevents liquid ink from spreading horizontally or soaking through to the reverse side. It allows gel pens, highlighters, and fountain pens to glide effortlessly while keeping notes extremely crisp on both sides.

Can standard A5 and B5 loose-leaf paper fit this binder?

Yes, this binder note system is fully compatible with standard Japanese loose-leaf paper refills. The A5 version accepts standard 20-hole sheets, while the B5 version fits standard 26-hole sheets. Matching the exact hole count ensures smooth page turns and prevents loose paper from tearing out of the binding.
