Description
Experience the Octopus Fluids Document Ink Brown, a highly reliable document-proof fountain pen ink, developed for professional users who value legally compliant and long-lasting documents. The high-quality, pigmented material guarantees a strong, clear typeface and meets the strict requirements of the DIN ISO 12757-2 standard, tested by the renowned Papiertechnische Stiftung (PTS) in Heidenau.
The brown ink stands out due to its excellent water, light, and smudge resistance and remains resistant to many chemicals such as ethanol, hydrochloric acid, ammonia, and bleach. This makes it ideal for public authorities, notaries, courts, architectural firms, and medical facilities where permanent legibility and tamper-proof security are top priorities.
Packaged in a classic glass bottle with a screw cap, the ink allows for optimal flow in fountain pens with piston or converter filling. Thanks to reduced binders, cleaning the writing instrument is particularly uncomplicated. Furthermore, the ink is vegan and free of hazardous substances requiring labeling, impressively underlining the high quality standards of Octopus Fluids.
