Portable hole

A portable hole was a magic item.

"They fall for it every time."

Description
A portable hole was a circle of black cloth, sometimes silk, about in diameter. When not in use, the hole could easily be folded to the size of a handkerchief. The cloth was magical, woven from the webs of a phase spider and strands of ether.

Effects
When a portable hole was spread on any flat surface, opened an extra-dimensional hole to a non-dimensional space that was wide and  deep. The hole could be picked up as long as there was no creatures or items inside.

The spell plane shift was required in order to create a portable hole. If a bag of holding was placed in a portable hole both would be lost forever, but a rift to the Astral Plane was opened. If a portable hole was placed inside a bag of holding, a gateway was opened to another plane. The portable hole and bag of holding were both sucked in, as well as any unfortunate individual within.

A portable hole did not function within the phlogiston.
