The efreeti bottle is typically fashioned of brass or bronze, with a lead stopper bearing special seals. A thin stream of smoke is often seen issuing from it. When opened, the efreeti trapped within issues from the bottle instantly. Most times, the efreeti will serve the bottle's master by providing three wishes per day. However, occasionally the efreeti will have been driven insane by his captivity and attack immediately upon being released.
