This strange inter-dimensional device is exactly the same in appearance as a portable hole. 

Anything placed within it is immediately cast into another world—a parallel earth, another planet, or a different plane at your option or by random determination. If the well is moved, the random factor again comes into play. 

It can be picked up, folded, etc. just as a portable hole. 

Note that things from the world the well touches can come through the opening, just as easily as from the initiating place.
