Sight Unseen Case - Mark Strivings (SM4)

The Most Versatile Device of Its Kind Anywhere...

The hottest utility item in decades! You get a business card case that looks completely normal but allows invisible access from the outside to the inside. It can be handled completely normally and casually and will not reveal its workings. It is very low tech, so nothing can go wrong. The access is built into the design of the case and allows for literally hundreds of effects and applications. You can perform nail (or boon) writing, pocket writing, billet switches, loading and unloading billets, peeks and glimpses of written material, double writing applications, use it as a hold out, as well as dozens of other possibilities that have yet to be discovered.

Your case comes with a booklet of some of Mark's own handlings for it, as well as descriptions of several techniques that will allow for any number of original effects.

LIKE NEW, with instructional booklet.
