This came from an old magic shop buy-out. New old stock; never used. The folded silks have never been opened out as can be seen from the picture. The back of the original packaging envelope has two stains from the old style scotch tape used to keep the envelope closed. Otherwise the envelope is quite good.
Effect: Just pass these two differently colored twelve inch silk handkerchiefs through your hand and they will change into two completely different colors!
You can change them back to the original colors if you wish.
No sleight of hand required.
