The Stealth Invisible Ink Squeezer – 10mm Mop is a compact, squeezable marker designed for smooth, controlled application of Stealth’s UV-reactive invisible ink. Featuring a 10mm mop tip and flexible body, it allows you to control ink flow by adjusting the amount of pressure applied while writing. The specialist ink applies virtually invisible before reacting to UV light and gradually developing into a dark brown to black shade. Its compact size, responsive squeeze action and flowing mop tip make it a versatile choice for creating bold, expressive marks with excellent ink coverage.

How to Use

Shake the Stealth Invisible Ink Squeezer thoroughly before use to ensure the ink is properly mixed. Hold the marker with the 10mm mop tip against a suitable surface and gently squeeze the body to control the amount of ink flowing through the nib. Increase pressure for a heavier, wetter application or use lighter pressure for greater control. 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 tip from drying out. Refill with compatible Stealth Invisible Ink when required and always test on a small area before use.
