BEn niu 777 Plastic Playing Cards

Using advanced printer marking technology and high-quality invisible ink, we print invisible marks on the back of each BEn niu 777 card. These hidden marks are not visible to the naked eye, providing a clean, discreet appearance. Players need to wear infrared contact lenses or professional infrared sunglasses to see the marks. This technology makes the marks highly resistant to fading, ensuring consistent performance. With this, you can cheat safely and confidently in any game.
