The “Tomoe River” paper used in the planners is thin and smooth to write on, which is one of its special features. However, depending on the type of pen or ink you use, the amount of ink, or your writing environment, the ink may take longer to dry and could cause feathering or show-through.

We recommend testing your pen on a less visible page first, or using a pencil board or blotting paper to prevent smudging.
