The Stealth Invisible Ink Calligraff – 1mm–4.6mm Chisel Tip is a precision marker designed for controlled lettering, detailed line work and calligraphy-style applications using Stealth’s UV-reactive invisible ink. Featuring a versatile chisel tip capable of producing lines from approximately 1mm up to 4.6mm, it offers excellent control over both fine strokes and broader lettering. The specialist ink applies virtually invisible before reacting to UV light and gradually developing into a dark brown to black shade. Its slim marker body and responsive chisel nib make the Calligraff ideal for precise, expressive work where line variation and accuracy are essential.

How to Use

Shake the Stealth Invisible Ink Calligraff thoroughly before use to ensure the ink is properly mixed. Apply the chisel tip to a suitable surface, adjusting the angle of the nib to create lines ranging from approximately 1mm to 4.6mm. Use the narrow edge for fine details and the broader face for thicker strokes and lettering. The ink will initially appear virtually invisible before gradually darkening through exposure to UV light. Replace the cap securely after use to help prevent the nib from drying out, and always test on a small area before use.
