This magic item is invented by Youngho-Park and also collaborated with Aboutmagic.
Many magicians praised him and his original trick.
This is 'FISHING CARD' by Park Young-ho, a magician who sold out the product after the 2018 FISM session.
The effect is very simple.
It's a magic trick to find the signed audience's card with a fishing rod.
You don't need to do a force or a deck switch.
That's how easy it is.
