The concept of the finger shell may be as old as the thumb tip. Japanese magician Sinada has developed the most practical modern version. Jay Scott Berry has taken the Sinada Gimmick to the next level. By adding a secret flap to one side of the gimmick, he's made it capable of holding many more items for productions, vanishes and transformations of silks, sponges, banknotes and more. With this gimmick, these items are contained within the gimmick, making it a self-contained unit which is much easier to palm and bring in and out of play.
