The juice marked cards are very useful as it is very difficult for a spectator to spot the marks on them. A special juice formula is used here and the signs can be seen from up to 15 feet away. As the signs are difficult to read, these cards are perfect for magic tricks.
Marks extra hard to see
Another advantage is that the juice marked cards cannot be detected by the famous riffle test. In a few words, the marks are impossible to be spotted. The markings are placed on the cards very carefully. You don’t have to be an expert, what you need is to know the secret.
All the cards are marked. There are 13 different marks related to each different card – 1-10, jack, queen, and king. The instructions of how to see the signs come with pictures showing how the marks look, where are situated and to what number they correspond.
Since there is no chance of spotting the marks, these decks can be inspected before a game or show.
These cards are for entertainment purposes only! Using them in hazard games is inappropriate.
