 SCP-067 is a fountain pen. It is pale green in color, with a single red line going straight down along the side. The shell is oak, and the nib is extremely sharp, capable of piercing human skin if pressed even lightly. Though it apparently lacks a reservoir, the nib never appears to run out of fresh ink. In addition, the pen writes an iron gall ink, which is suitable for artists but would normally corrode typical fountain pens quickly. Research has surmised that any subject holding SCP-067 loses all autonomy of the hand and arm that grasps it. Full sensation is intact, but the arm below the elbow is controlled by unknown forces, theoretically centralized within SCP-067.
