A bold deck switch using a Card Case Shell was published by Robert Parrish in his trick “Synchronism” in Do That Again!, 1939, p. 35. He uses a card case with a lid and places the lid on the wrong side of the case similar to an Okito coin box to build an impromptu shell. Virtually the same choreography as employed by Parrish was later reinvented by Dean Dill and used in his marketed trick “Blizzard” (1997).
In 2012, Christian Engblom marketed “The Cooler”, a clever mechanical card case shell manufactured to switch a deck.
