This is a mug shaped like a rum barrel with barnacles and seaweed clinging to the side. This fourth edition of the mug has a has a matte beige (with yellow tint) wipe-away finish with matte teal blue still left in the recesses. The interior is a glossy clear glaze. It appears to be a new sculpt and is slightly smaller than the previous editions. Used to serve the Shipwreck on the Rocks cocktail made with Maker's Mark bourbon, freshly muddled lemon and mint with organic agave nectar.
