Not all of these pens were given out in 2012 because this one was in the goodie bag for attendees of the 7th European Magic History Conference in Turin, Italy in 2017.
This was a gift given to all attendees of the FISM magic convention in Lausanne, Switzerland in 1991. The novelty is that when a coin is dropped through the slit in the top of the box, it immediately vanishes, although it can still be heard rattling around in the interior which apparently contains no more than a top hat floating in mid-air. This is a well made puzzling illusion. US Patent No. 4967953. Created by Tenyo. Made in Japan.
This was a free gift received at the 5th European Magic History Conference, Hamburg 2013. Provided by Hanky Panky It’s Magic, it was originally produced for the 25th FISM in Blackpool, 2012. Made by Hanky Panky Toys (Thailand) Co Ltd.
