The Tenkai palm is a card magic technique used to palm a card.
[1] It was invented by the Japanese magician Tenkai,[2] whose real name was Teijiro Ishida (1889–1972).
The Tenkai palm has many applications in card magic, as well as other manipulative magic with objects of a similar size, such as jumbo coins.
Additionally, the Tenkai palm allows a great deal of freedom in the methods of concealing and revealing.
