Double 12 marked dominoes
Seldom people use Double-12 dominoes. However, we can offer you marked dominoes of double 12 when you needs.
The marked dominoes work with invisible ink reader as a kit. You can just wear infrared contact lenses or luminous ink contact lenses to see the invisible ink marks. People can see nothing different on surface of the back between normal clean dominoes and our marked dominoes.
Usually we buy the high quality normal clean dominoes in China and then mark them with advanced invisible ink by special machine. These dominoes can be white, beige, red and so on. If you can't find the ones you use in daily life here, you can also send me your own dominoes from your country then our technicians will mark them with luminous ink marks for you.
Please note that cheating devices are forbidden in gambling and in some countries are punished by law.
