The Bicycle Glider Back deck is a 100% custom deck of playing cards featuring origami-inspired artwork. The back design has paper gliders in an appealing geometric layout against a vibrant blue background. The traditional-looking back also contains a devious but easy-to-learn coded marking system that allows you to identify the suit and value of each card. We sent a sample deck to one of the world's foremost experts on marked cards, but we didn't explain the system to him. His first response was, "I tried to work it out with the riffle test - couldn't see ANYTHING - I did eventually work it out but d*** that is well hidden. I was starting to wonder if you were winding me up!" So before you view the instructions on how to read the cards, see if you can figure out the system on your own! The court and spot cards are designed to look as if they've been folded out of paper, and the whole package is contained in a striking custom tuck box with a custom seal. Printed in the USA on traditionally-cut Classic stock with embossed Magic finish by the United States Playing Card Company, Bicycle Glider Back playing cards are printed using vegetable-based inks and starch-based laminates on FSC-certified paper sourced from sustainable forests. This means the cards not only shuffle, fan, and spread perfectly for all of your favorite games & tricks, they're made with the environment in mind! o100% custom artwork oFully marked for suit & value with coded system oPrinted by US Playing Card Co. oClassic stock with embossed "Magic" finish oTraditionally cut oCustom tuck box with custom sticker seal o2 gaff cards included oLimited print run of 2,500 decks
