Invisible Ink Stamp Coach Guide
We're using alcohol based "blacklight" ink, which fluoresces and emits light under UV light.
Saturate the stamp pad - this will last for hundreds of inkings.
Clean and dry your stamp with household cleaner before using - otherwise prints WON'T be invisible!
Stamp message or pattern - we like dark colored paper. Takes +/- 2 min for marks to dry completely.
All marks hadn't dried yet - look how brightly they react under UV! It also looks awesome on skin!
