Selling a White Silk Bag, described here

While the Invisibility effect doesn't really help you when hunting, it DOES help in the Heist where you need to be stealthed/invis in order to get better rewards. My sorcerer was getting max rewards from the Ophidian Cabal without any ranks of stealth, since they only require that you be stealthed/invis and not to pass a skill check
Also, it holds much, much more than a waist slot is normally allowed to
