The Secret of the Sea is a deluxe deck of playing cards about pirates and sailors. The Deluxe Limited version of the deck features coloured court cards with a gold foil border and a back design with gold foil, a black background, and blue foil waves. The tuck box is manufactured by Boschiero & Newton in Italy with three hot foils and embossing. The Deluxe Limited edition features the same cards as the Kickstarter Exclusive Blackbeard edition but without the holo-blue gilding. This version was not available during the campaign but was released after fulfillment on the Fris Cards website.
