Noodler's Ink -- Today I bought a bottle of black Noodler's ink at NK, Hamngatan in Stockholm. They had a large selection of colours (Thanks, Tomas). The 3oz bottle cost SEK 129 (approx. $19 USD). To my surprise, the seller did not know it was waterproof!
Note: "The waterproof/fraud proof line (currently black only) cannot be altered on a check or envelope by rain or bleach/ammonia. They consist of over 97% water content...and rinse (or simply rub) off lucite/celluloid/acrylic rod stock testing and ebonite testing stock...and if dried in the bottle it can be reconstituted with tap water...but once on cellulose paper they stay on it as a bulldog biting the leg of the enemy despite rain/soaking and the soaps of a check forger. One word of caution - if mixed with conventional ink the fraud proof ink WILL REVERT TO CONVENTIONAL INK and all those properties will be lost. It is a delicate formula best left alone if one wants the features to remain constant."
