1 - mechanical pencil size 0.5, lead: HB
2 - a normal plastic eraser (soft) and a pencil eraser for precise erasing
3 - Copic multiliner sepia, size 0.05
4 - Copic multiliner black, size 0.05
5 - Copic ciao (two nibs: broad and brush)
6 - Copic classic (two nibs: broad and thin)
7 - Copic sketch (two nibs: broad and brush)
8 - Tria marker (three nibs: broad, thin and very thin)
9 - Copic "Blender" classic, number "0"
10 - opaque white (I used water colour opaque white)
11 - a round brush, size 00
12 - a round bristle brush
13 - a round screen
14 - marker paper, size A4
