Temporarily through with Mal's laundry pile, The Prop Store of London is going through Inara's things. Check out this ornamental box.

An ethnic ornamental box used in the sci-fi adventure Serenity. This decorative ornate is made from metal was used as set dressing in Inara’s room. Measures approximately 15cm x 6cm (6” x 2.5”)

This may be gone already — Serenity props under $100 tend to sell quickly — but it can't hurt to check.
