Any questions?
Where can I get notebook inserts?
Both journals come with a notebook featuring a dot grid pattern. You can order more notebooks from the following options:
Will this fit my current notebooks?
Our journals are designed to fit most softcover notebooks that are about the right size for each journal.
As long as your notebook’s thickness (width) is under 1", it should fit perfectly!
Just check your notebook’s dimensions to be sure.
How many inserts fit?
Each cover holds up to four notebook inserts with elastic bands.
You can mix and match different layouts—tasks, planning, notes, and more—to create your own system.
Does it work with fountain pens?
Absolutely! Every journal (except A6) comes with one Dot Grid Tomoe River notebook—known as one of the best papers for fountain pens.
It resists bleed-through and feathering, so your writing looks crisp and clean.
