I was initially surprised by how flimsy it was and its 3D printed body but, assembled, it does the
trick quite nicely. If you're not familiar with the actual technique of vanishing the bill or
whatever, you'll soon see how it's done and may do away with the gimmick altogether. My manual
dexterity suffers from occasional inflammation and arthritis, so a handy little gizmo like this is
great in a pinch and also serves to condition my fingers to do the vanish without the gimmick. Hands
up a great idea.
