An age-old gambling principle built into a modern design.

The Ruby Duos are a uniquely edge-marked deck that lets you locate any card from a shuffled pack without looking at the faces or even spreading the cards. Think of them as an instant memorized deck.

The branding has been carefully crafted: the focal dots serve as subtle misdirection, drawing the eye away from the lined pattern that cleverly encodes the identity of every single card.

Printed on Hanson Chien's legendary stock with a vintage finish, the cards feature a traditional cut. They faro perfectly straight out of the box and strike the perfect balance of softness and snap.

The tuck box is printed on durable synthetic paper, designed to last. The deck comes in Aronson stack straight out of the box and includes a blank face card and a double backer, completing the 54-card set.

Over a year in development, the Ruby Duos are the result of countless iterations by Jake Banfield. The unique horizontal line pattern helps eliminate common border width issues during printing, and the symmetrical design means the markings are readable from either beveled edge-no matter how the cards are shuffled. Printed on white stock with a crisp white border, the Ruby Duos are also ideal for all your favorite working sleights.
