I use this paper to take notes, and I mostly use fountain pens.

Any ink I have used works very well and there is no feathering, bleed-through, and minimal shading. Either side of the sheet is fine when writing on both sides.

Writing on this paper is smooth with rollerballs and fountain pens, and grabs the ink consistently. Practical and enjoyable.

The A6 sheets fit in the A5 planner which allows you to place it where you like if you, like many William Hannah customers, have more than one of these systems.

Buy as many as you need. They are great!
