The chest's core is made of a light, brownish-pink wood, with the corners and edges being covered in a golden frame that appears to be attached by bolts or rivets. Its body is rectangular and the lid is rounded off.
There are golden handles on either side and a key-shaped hole at the front. Aside from the lighter color, it looks very much like a stereotypical treasure chest seen in films, television, and various video games.
The chest's contents are yet to be revealed, that is if it has any. It currently rests inside of Lion's Dimension, on the hill and under the tree next to Rose's other possessions.
Like most of the items, Steven isn't seen interacting with the chest, though it seems to be still in the dimension, as seen in "Bismuth". It's unknown if Steven has opened it yet, or if he even can.
