In 2014, a highly select group of mentalists were given access to a card holder that incorporated a new kind of peek.

At the time of its release, the holder's ability to provide a quick, simple and undetectable peek earned it a reputation as one of the best peek wallets in existence.

Although a host of performers have since attempted to get their hands on one of the few available units, their efforts have consistently proved unsuccessful.

Until now.

Viper is back - and it's more powerful than ever.

Viper is a stylish leather card holder, but its innocent appearance conceals a diabolical secret that enables you to read people's minds.

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, unless you decide otherwise...

The Viper system gives you a full peek of anything that can be written on a business card.

You can also use Viper to peek the contents of a folded piece of paper... And, just to push things even further, we've made sure that Viper can give you access to written information from multiple spectators in a single peek!

Viper can also be used to load and steal business cards, billets and playing cards.

With its natural, slimline form factor, Viper can be easily slipped into any jacket or pants pocket.

Viper is designed to be used as an everyday item, and can carry your credit cards, business cards and loyalty cards.

Stylish, stealthy and powerful, Viper is an indispensable tool in the modern mentalist's arsenal.
