Infrared glasses to read invisible ink

I need a kit of lenses (IR? UV?), pen and invisible ink to make magic tricks to friends. I’ve seen people selling it to cheat in poker, but for its nature that trade was secret, expensive and probably illegal. I need instead something cheap and safe. My budget is 50 €.

It is expensive, yes, but not illegal. I do not endorse the site or know anything about it.


I am using contact lenses to see invisible ink to playing cards . It is really helpful for me . I bought the contact lenses from spy cheating playing cards in Delhi. I use this trick and won many games in casino . i think this contact lenses work on whit paper too. I will surely try this and let you know about this .


you can buy high quality soft contact lens from rsjk spy card shop. They are good dealers of customise contact lenses and spy invisible playing cards in Delhi


I don’t think any lenses would make you see IR or UV. It’s more probably polarizers.

But I’m interested to know !
