The plotter came with nice wood boxes for holding the accessories. The front box on left is original on loan to me. The back box is a reproduction I made. The plotter had accessories for ball point pens, pressurized ink pens, liquid ink technical pens, and felt tip pens. I used all over the two days. The clear parts are sights for aligning the plotter pen with preprinted graph paper. Paper expands and contracts with enviornmental conditions. The plotter has a dial that can adjust its movement so it stays aligned with the graph paper for right and left movement. The pins feed keeps the paper aligned for up down movement.
