From Wikipedia:

Magic satchel is a term often used in reference to role-playing video games. It refers to the use of a character's inventory in the game, which can often contain more items (or items of too large a size) than is physically possible for the character to carry without any visible means to hold or transport them.

A similar concept is hammerspace, the term used to describe the seemingly invisible place from which fictional characters, such as cartoon or anime characters, pull out very large objects, such as mallets. Technically the term hammerspace is not used to refer to a magic satchel itself, but rather the area or pocket of space that a magic satchel utilizes; a magic satchel is like a door to hammerspace.

Ramona Flowers from Scott Pilgrim VS The World used a small bag that had the same exact concept, where she would hide very large weapons like her giant mallet.

Like Spider-Man always says:

With great power comes great responsibility.
