Stealth Ink Squeezer [80ml]

The Stealth Ink Squeezer is an 80ml squeeze marker with a 13mm mohair nib, filled with a colourless, water-like ink that stays invisible until it reacts with UV light. It appears almost instantly in direct sunshine and more slowly in shaded spots, settling into a shade from dark brown to black. Very permanent on absorbent surfaces and almost impossible to buff, it’s a distinctive choice for a slower, stealthier reveal.
