Polar Blue

Noodler's Polar Blue is a bulletproof, eternal blue ink renowned for its high water, bleach, and light resistance, making it ideal for permanent documents like checks and official writing. It dries very quickly without feathering or smearing, though it may bleed through thin paper, and offers a flat, pastel-like blue with low saturation and lubricating properties for smooth flow. It suits professionals, artists needing permanence, and users in cold climates due to its freeze resistance.
