In my opinion, brainstorming needs a smooth flow of ideas. For this purpose, I usually use:
- High density blank papers. Using a metal clip, I bind some A4 papers that have been used on one side
- A dark pencil; preferably a 4B
- Easy flowing pens; such as Kores, Papermate Profile and Bic (I don't know the name of the one in the picture but it is awesome)
- Sometimes a marker is also handy
To have a neat plan I also use:
- A squared note pad; Rhodia is a good one
- Fine pens, I could not find anything better than Stabilo Point 88
- An HB Pencil
- An eraser which can also be used to hold my phone
