1.The A4 Drawing Board comes with Metric System. The board outsize size is 38x30cm and its inner sheet size is 35x27cm.. The drawing board is made of unbreakable Acrylic material for durability and the drawing surface is very stable and solid for any design project. 

2.The parallel straightedge with STOP and GO locking/unlocking action guides your drafting precisely. Dual rail system is handy for ensuring straight lines, as well as clamping the paper securely in place. And the board is marked in centimeters on both edges.

3.On the drawing surface there are two options for secure fixation of the sheet, which can also be operated well with one hand. This is especially important for completing a title block, as all letters are on an imaginary line.Once the sheet has been clamped and the rail has been inserted, nothing wobbles on the sheet, so you can work properly. 

4.The long straightedge design allows drawing along the top edge of the straight edge right down to the bottom of the sheet, with full accuracy and stability. And the triangle ruler and angle ruler are all equipped with slot so that it can be moved left and right on the long parallel ruler.
