Multigraph pencils, Intense copying, yellow box, Eagle Pencil Co., New York, copying pencils, 6 pencils in box, gold tipped pencils
I'm not sure what these intense copying pencils are used for - maybe you do. These are old but appear unused.
These pencils can be viewed as a predecessor to the ball-point pen. They were convenient (no need to continually dip one's pen into the ink well), provided firm pressure (superior to fountain pens of the time), and generated relatively permanent markings. Their usefulness is demonstrated by the wide range of applications to which they were enlisted.
Condition: The box shows wear around the edges. Someone has marked a previous price on top of the box (hate it when that happens).
