TONGLE 308 Plastic Playing Cards

Color back cheating cards can also be marked for infrared camera lenses, which cannot be seen by invisible ink contact lenses or infrared glasses. They can only be seen through infrared camera lenses. If you offer a place to play poker games, marking cheating cards and infrared spy camera kits are a good choice for you because they are undetectable by poker glasses and are very secure. However, you need to have a partner who can read the invisible marked card sets for you in another room.
