Orgrimmar 5 Pcs Art Ruling Pen for Applying Masking Fluid Line Work

All 5 of them are the same. What worries me is the turn disc. It can easily be off the screw and get lost.

These lack any precision in manufacturing. Either one side or the other (not the same side all the time) is longer than the other. They release ink poorly. It’s hardly fair to compare them to my vintage German made ruling pens from the 60s, but having used those I know how truly poor quality these are. Perhaps they would be okay for masking fluid but I wouldn’t count on it.
