Many poker players always ask us the same question, do you have invisible ink or invisible ink pen for sales? The answer is yes of course.
Our company offer you the ink that can help you to mark the red cards for contact lenses, and the red and blue cards for IR camera. If want blue cards marked for contact lenses, better let the cards marked by our factory.
Why? Because invisible ink seen under contact lenses is black, so black color face to blue color, it is very hard to be distinguished.
The ink can be dry after 5 seconds and can last for more than 3 hours. Very useful ink for you.
The invisible ink can mark both paper cards and plastic cards. Invisible ink, luminous ink and laser ink are available in our company. If you want to mark cards by yourself, you can pick up any one of those ink as you like. They all are high-quality ink.
