This is an excellent switch utility. I read one of the reviews that said that his friend wanted to
inspect the box after the performance. I see how this would be the case when doing a color changing
card or a dollar bill to coin type of visual transposition but it is super spy deceptive for other
applications. With the right routining you can use this to do an incredibly clean signed--yes
signed, dollar bill serial # divination or you can have someone put any face down card into the box
and switch for a card to impossible location. What is more innocent looking than a empty card box.
