This is a vintage pre-owned item we acquired from from an old magic estate. It’s in good working order and comes with a copy of its original instructions and the original packaging envelope.
This is a well made cloth blindfold. When placed up to anyone’s eyes they cannot see through it. Still, when it is tied around your head covering your eyes you can see well enough to describe people, read things written on a blackboard, drive a car, in fact you can do most anything you would do without a blindfold.
The instructions describe many unusual effects which you can do with this.
