This box is created in a way that ensures the dice rotate only once per shake. Max Maven discovered an ad for “The Mystic Box and Lucky Die,” in Floyd Thayer's The Magical Bulletin, Vol. 7 No. 10, Oct. 1919, p. 111, but the box is probably far older. Bridger Lewis, in Magic Wand, Vol. 45 No. 251, Oct. 1956, p. 103, reports that it was a favorite pocket trick of Chung Ling Soo.
