Invisible UV Ink
> An all-purpose UV ink that is invisible under normal lighting conditions, but under UV light (blacklight), it glows a bright blue.
It is the same formula used in our Invisible UV Marking Pens. Perfect for hand stamping at events and document marking.
Add to our empty Stamp Pads for use with rubber stamps.
When dry, the ink is fairly water resistant, but can be washed off after several washings.
Invisible UV Ink, 4 oz.: $7.95
Invisible UV Ink, 8 oz.: $14.50
