"An uninflated rubber balloon."
Balloon (風船 fūsen ) is an item in Resident Evil 7: Biohazard.
The Balloon is to be placed over the gas pipe in the main room, allowing it to inflate and blow out the Quill Pen.
The Balloon can be found in a corridor filled with inflated balloons. If the player does not know where to look, they should crouch and use the lit Candle to pop them.
