Stamp Inks

UV (security/sympathetic) Invisible Ink - 4 oz Bottle

The invisible ink we offer has been tested and approved as safe to use on skin. This special purpose ink is revealed when exposed to a UV Black Light wavelength of 200nm to 400nm. This non-toxic formula is semi-permanent. Ink cannot be easily washed away by just water or sweat. It can be removed with soap and water or it will self-evaporate from skin within 2-4 days. It offers quick drying times of no more than 15 seconds making it an ideal solution for high-traffic events.

Note: Invisible ink is alcohol based and will evaporate over time, an air-tight stamp pad is recommended to help extend the life of the ink on the pad. UV ink is not recommended for self-inking stamps, as it will ruin the ink cartridge over time and you will need to reink it everyday.
