Looking carefully at the pictures is the best way for you to determine condition! I am not a collector and it would be difficult for me to try to do so, but I do want to point out.........

This is an estate sale find. I believe the pen is unused but I marked it as used as it was preowned

I will have several Castell drawing pens on eBay..a few did not have their instructions. I made copies of the instructions and will include them with the pens that didn't have them.  I am also happy to combine shipping on the pens..just let me invoice you with the total shipping cost
