Polar Purple

Noodler's Polar Purple is a bulletproof, water-resistant purple ink from the Polar series, engineered for fast drying, wet flow, and freeze resistance to prevent pen damage in cold conditions. Known for its archival permanence against forgery tools, UV light, bleaches, and solvents, it performs best on quality papers like Tomoe River with fine nibs despite some feathering on cheap paper. It suits users needing durable writing for documents or harsh environments, though cleaning may require effort.
