Bag

The bag is a miscellaneous item in Fallout and Fallout 2. There are two separate items in the game, but they are covered on a single page as they have the same functionality, price, and bugs.

Characteristics
The bag can store up to 20 pounds of gear and is a useful item for segregating the inventory.

Fallout

 * Katrina in Shady Sands has one.
 * Sold by a trader in the east part of Shady Sands.
 * Another one can be found inside Gizmo's Casino in Junktown, on a bookshelf in his personal room.
 * Sold by Killian Darkwater in Junktown.
 * One on a bookshelf in Jon Zimmerman's basement in Adytum.
 * A rare version of the bag can be found in the Los Angeles Vault, on the top floor in a locker.
 * The wandering (random encounter) merchants Terrance and Julian carry the rare version of the bag.
 * Random encounters on the coast sectors.

Fallout 2
The only bag in the entire game is in Modoc's caves, in the bottom-left tip of the crescent formed by the rat's nest. It requires pinpoint accuracy to tag and obtain.

Bugs

 * Bags are generally heavily bugged and should not be used; for instance, a bag containing a quest item that's supposed to be removed from the inventory by a script will prevent the item from being removed.
