The ingenious Viper system gives you instant access to any written information (text, drawings, numbers, etc.) that is inserted into the card holder.
As soon as the information is placed into the holder, Viper can immediately be closed. Whenever you need to, you are then able to see - clearly and in full - exactly what your spectator has written, without having to open Viper again, or perform any suspicious moves. You can even show Viper on both sides - there's nothing to fear, because there's nothing to see.
Viper can also be used to load and steal business cards, billets and playing cards.
Stylish, stealthy and powerful, Viper is an indispensable tool in the modern mentalist's arsenal. With its natural, slimline form factor, Viper can be easily slipped into any jacket or pants pocket.
