As with most tricks purchased here, you'll get a "learn" video that can be downloaded to your device and manipulated in any way that you'd like ;-)
Oh...no printed instructions.
I've had this for years...it's a fun effect (and very easy to perform...)
One more thing...although you'll get plenty of card gaffs, you may want to consider refills which are available as a single pack...or a 3 pack saver.
Best wishes.
