Invisible UV Ink
> A solvent based UV ink that is invisible under normal lighting conditions, but under UV light (blacklight), it glows a bright neon blue. Not for use on skin, this solvent based ink works great on virtually any surface. Unlike our all-purpose UV ink, this an industrial grade permanent UV ink will not wash off. Perfect for marking tools or other items that need a permanent UV mark.
NOTE: As this ink is a solvent base, it is flammable, harmful if swallowed, and may harm some plastics.
Not for use with Stamp Pads.
