The drawing board size is 30cm x 42cm. There is a paper clip and a compass on the top, and a nylon bag on the bottom, which can store drawing tools such as paper, triangle ruler, pencil, rubber, compass, etc. The sling of the drawing board is slanted on the shoulder, and the drawing board forms a flat table in front of the chest, which is very convenient for on-site drawing, especially for on-site traffic drawing.
