Invisible Ink To Copag Playing Cards

Have you ever heard of COPAG cards? The history of COPAG cards is directly related to the history of card games in Brazil. In 1908, the COPAG company was founded by Albino Gon Calves in Sao Paulo. Since its establishment, COPAG has maintained its absolute position in its industry.
Copag marked cheating cards are made from 100% plastic, and we also have Copag marked paper playing cards. Copag marked playing cards can be marked in different ways: red cards are marked by invisible ink with big font in the middle or small fonts in 4 corners (white or black marks), blue cards are marked by invisible ink with big font in the middle back (white invisible ink markings). Those invisible ink marks can be seen only when wearing our infrared contact lenses.
