"The black bones of zee-monsters make for startling corsets."

Obtaining

 * Buying from the Chelonate at Uncle Ankle's Lean Place for 26 echoes apiece or from Khan's Shadow for 27.
 * With a Zubmarine, buying from Nook at The Yawning Maw for 26 echoes apiece or The Gant Pole for.
 * If Nook or Chelonate spawn near Polythreme, this becomes a decent "trade opportunity" (as far as those go), you could even cycle it if you use the nearby Dahut for terror and supplies. However shop-to-shop trade in general is not a profitable way to spend time in Sunless Sea. You're generally better off hunting monsters and doing port report runs. Trading is something you do a bit of along the way if don't have a better use for your cargo space at the time.
