Noodler's Ink Refills Whiteness of the Whale Bottled Ink

1 ounce of ink per glass bottle. Whiteness of the Whale is considered to be harpoon-proof, which means that it is archival, waterproof and also glows under black-light. The milky white appearance of the ink in the bottle spreads completely clear once it hits paper. It appears nearly invisible on the page, but glows under blacklight. Artists and fountain pen ink collectors use this ink to tint other colors of ink by mixing different ratios of colors together.
