- For the flatpacked version, see Oak treasure chest (flatpack).
The Oak treasure chest is a piece of furniture that can be built in the Costume room of a player-owned house with the Construction skill. The oak treasure chest can hold storable rewards from low-level (level 1) Treasure Trails. Building this chest requires at least 48 Construction and 2 oak planks. Treasure chests can be flatpacked and bought from the Grand Exchange. Building a flatpacked treasure chest does not require the actual Construction level.
