Phase Spider's Silk Pouch

This sturdy pouch is made from the silk of a
Phase Spider. It can store a seemingly infinite
number of coins and gems. No other objects
are able to enter the pouch. The owner is able
to easily withdraw anything the pouch contains.
No jingling sound can be heard from the pouch.
If the pouch is damaged from the inside, it is
destroyed, and its contents are scattered in the
Astral Plane.
If the pouch is turned inside out, it empties.
It must be put right before it can be used again.
