The Stealth Ink Calligraff Marker is the ultimate tool for those who prefer to work in the shadows. Pre-loaded with the legendary invisible Stealth formula, this marker allows you to leave your mark completely unseen. The magic happens when the ink meets daylight: UV rays act as a developer, causing your tag to gradually emerge and darken.
Equipped with a wide 20mm tip, this marker is perfect for large, calligraphic handstyles that will surprise everyone once the sun comes up.
Technical Specifications
Volume: 80ml.
Tip: 20mm Broad Calligraphy Tip.
Effect: UV-Activated (Invisible to Dark Brown).
Permanence: Extremely high (Surface-penetrating).
Build: User-friendly "Calligraff" body for smooth flow.
Durability: Smudge-proof, waterproof, and nearly impossible to buff.
How It Works
Apply: Write on almost any surface. The ink goes on clear and is virtually undetectable.
Develop: As soon as the tag is exposed to UV light (daylight), the chemical reaction begins.
Darken: Direct sunlight works best. The tag will turn a deep, permanent dark brown that bites into the surface.
Stay: Because the formula penetrates the material, it resists standard cleaning agents and "buffing" attempts.
Why the Calligraff Edition?
Invisible Precision: Lay down wide, clean lines without anyone noticing a thing.
Large Capacity: The 80ml tank ensures you can cover plenty of ground before needing a refill.
Permanent Legacy: Once developed, the ink's long lifespan ensures your style sticks around for the long haul.
Note on Stats: While the body is built for 80ml and a 20mm broad tip, it uses a specialized internal valve system (often referred to in the 4mm-style technical family) to maintain a consistent, heavy flow to the large nib.
