Portable hole

Portable Hole Magic Device

This is a silky purple cloth circle, with a sticky fringe.

Value 12000 copper copper Weight 0.2 kilograms

Effects: When stretched flat over a solid surface, all but the fringe disappears, replaced by an extradimensional tunnel to the first large enough flat surface in a straight line from the portable hole, perpendicular to its surface. The extradimensional tunnel is as long as the straight line path was when the tunnel was created, and does not change if one or both of the surfaces are moved. The fringe becomes simultaneously extant at that location, and may be picked up from either end. Picking up the portable hole or destroying the surface it is on dispels the extradimensional tunnel. The portable hole has a Volume Ratio of 1 per every 5 meters of depth, rounded down.
