I found one of these in a used magic bin at a brick and mortar shop. I paid about 2 bucks less than that MJM has it listed for. I am pleased I picked it up.
Imagine, you remove coins from the purse and make them vanish one by one. You tell your spectator/s that the coins are homing coins and have them pick up and open the purse for them to find that the purse is now solid and coins could not have even been in it to begin with.
This item is something that I find that I will be using with my coin routines.
