Simple idea, beautifully made.The Shinwa erasing shield is a thin stainless steel mask that you lay over a pencil drawing to isolate the part that you want to erase and minimise damage to the surrounding paper surface.
“I hesitated to buy this but has been highly useful for very precise markings on wood which I constantly need to rub out or correct while I’m on a college course. It’s not expensive but it’s perfect for accurate correction so u can get those drawing bob on and not full of the wrong pencil marks.”
