I just bought a bottle of Parker Quink Black ink. The bottle doesn't say whether it's washable or permanent. Also I can't find a review of Parker Black on this forum. The box is silver. The bottle has a black label. The manufacturer's number on the stick on label on the box is :3011-00.
I would appreciate any opinions or experiences with this ink, including whether or not it's permanent and how safe an ink it is for nibs, feeds, and filling mechanisms.
Thanks,
Ron
