Frequently asked questions

How does the refill system work?

Slide out the old refill, slide in a new one. A minimalist elastic loop keeps each refill securely in place, with no rings, clips, or bulky mechanisms. The leather cover is designed to last for years while you swap refills as needed. Each B6 refill is sold separately. Every refill comes with a built-in bookmark ribbon located in the middle of the book. To insert a new refill, open to this middle page and slide it into the cover. Then adjust to ensure the ribbon doesn't get caught by the elastic loop.

How long will one refill last me?

That depends on how you use it. For most professionals who write daily notes, one 80-page refill lasts 4 to 8 weeks. Designers and sketch-heavy users may go through them faster. We recommend keeping 2 to 3 refills on hand so you're never stuck waiting.

What pens work best with the paper?

Our 64 gsm Japanese paper works well with most pens you'd use in the office, including rollerballs, gel pens, and many fountain pens. Minimal show-through and minimal bleed-through.
