NILLP Legal Lapis Ink - A Pendemonium Exclusive! Of all the inks we sell, Noodler's Legal Lapis is our NUMBER ONE best selling ink! Legal Lapis approaches traditional blue black colors, with far more blue and a striking vintage look to it, but the best thing about Legal Lapis is that it is permanent on paper, the solution for all your legal documents and for any applications where the ink must remain permanent on paper. Legal Lapis contains a special blue dye that remains water soluble UNTIL it dries on paper, then it becomes waterproof and permanent.
