This is a set of 5 Rotring Isograph pens. The set includes Isograph pens in sizes 0.10, 0.20, 0.30, 0.50, and 0.80, along with ink, a pen station, and a dedicated case. They were used a few times after purchase and then stored at home. The 0.40 and 0.60 sizes are not included. Ink is attached to the pens (except for the 0.80) and the case lid. Other than the above, there are no noticeable scratches or damage to the main body. They have been stored unused since then, so I am offering them to someone who can use them.
