Produce a butterfly!
Created by So Sato
 
In this truly unique magic effect, the magician magically produces a butterfly of a chosen color, on a pin inside a box that was previously shown empty. Every item used in this trick contains a clever gimmick, and the combination of these gimmicks produces an extremely baffling magic effect that is beautiful and easy-to-do.
 
The specimen box may also be used for other routines without a butterfly theme. For instance, the box allows you to transform or produce pieces of paper, or coins containing a central hole.
