A plain looking leather satchel.
This magical bag of holding seems to have an almost limitless capacity, but is S.D.C. in nature. Many a coveted item was aggressively thrown into this bag by characters (most notably Fluce) in the hopes that it would soon be forgotten by those who did not actually carry said bag. Often this tactic worked, and the holder was able to gather a large treasure hoard, virtually unnoticed by the others in his party.
