5-7/8 inch Ruling Pen, Bow Compass, small compass, and Eraser Shield for precision drawing and drafting.
The erasing shield has been designed to use as a mask for protecting parts of a drawing so that only the area exposed in the chosen cut-out is erased. The shield is paper thin and made from a flexible hard wearing foil. The cut-out shapes are precision cut so as to ensure a smooth line. Pick up in Brookline.
