Apply the loose-leaf design in the picture book, each page can be freely replaced, and freely make the most satisfactory portfolio. You can also change the thickness of the sketchbook at will to reduce the weight when you go out to sketch. The transparent framed cover allows the painting to become the cover for a one-of-a-kind sketchbook.

D1300: 106mm X 168mm
F2: 285mm X190mm
