I've seen in a lot of videos people with chests and storage compartments. How do I get these because I can't seam to find them in the market.

i'm also wondering this...still have yet to figure it out

Ive been stumped too i think its not used in that way purpose maybe just decor only. But if it exists might be a merit item.

There was a video showing the person opening it and it was bought from a shop that was in beta but is no longer there..atleast for the time being so maybe it hasnt been added.
