Delicate tissue paper & glass magic trick.
This clever trick is made with two folded sections, joined together at the center by a glass window. One side remains folded, and the other opened to show four cards plus one card behind the window. A spectator is asked to name any one of the four cards which he would like to see appear in the glass window. Whatever card is selected is folded over flat against the window. The packet is then secretly turned over. When re-opened the selected card appears in the center window.
"Made in Japan." Measures 5" x 3-1/2" when opened.
