Korobox by Sultan Orazaly

Description

An impossible mind blowing penetration effect that you can easily make at home.
A great solid-thru-solid illusion! 

Show a matchbox and insert a coin into it – the coin fills the box with very little free space remaining. Now you pierce the box with a knife, apparently going right through the coin (there’s nowhere for the coin to “hide”)! Open the box and show that the coin is still inside! 

Looks amazing and very magical!
