The creative minds at Creative Magic have just released their “Pandora Bag” which is a drawstring bag of white see-through netting material with a black-velvet boarder. The spectator(s) can add their own contents, yet you have the ability to force (or change) an object, will work best with things like billets I think. A lovely idea and well made utility-prop,that does not have that “magic shop” gimmicky look!
It has some subtle touches unseen in force/change bag
The good thing about this force bag is that you can hold slips of paper/ billets/ etc in a compartment near the top of the bag. This means you are free to release the force items when you want. This can make the bag look empty before adding billets. A great bag for mentalists.
