I think that this drafting ink pen is very good general pen for drawings of highly complex and / or detail precision equipment . I use it regularly and appreciate how well it works for ink drawings and how layout lines are quick & uniformed . I would recommend that it is better to use over pencils drawing that smear and it is darker than pencils for better reproduction copies . However , I do wish that a nib key ( wrench for the pen point ) come in the set !

I love it.
