HARD CASH by Nhan and Vkun

This is visual eye candy at it's best. HARD CASH has taken bill changes to a new level. A powerful new method to visually change the bill on both sides in the mid-air. It’s so super easy that you almost do nothing, the self-contained gimmick does all the works for you. 

Gimmick construction and handling included.
