This is a small ceramic jug of rum with a skull and crossbones on front, labeled "RUM", with handle and cork. A few barnacles clinging to the sides.
Designed by Squid and produced in a matte brown first edition and a darker more satin brown second edition. There were also Artist Proofs in a variety of colors.
From Lost Temple Traders:
"While we were hunting for pirate gold on a recent salvage trip, we came across an even greater treasure - 150 bottles of rum perfectly preserved by the ocean floor.
Our initial goal to drink them ourselves proved to be daunting so we’re making them available to you.
Designed by SQUID, the Rum Jug Mug is a Limited Edition of 150. It stands 7 inches tall and holds 16 ounces of your favorite cocktail."
