From Dynasty:

"A riff on the classic rum barrel mug, the Rum Drum takes inspiration from the many indigenous-made drums of Oceania. Some say a ship was wrecked off the coast of a rugged island and a tribe scavenged the wreckage to make this instrument. Others believe sailors inspired by the indigenous drums crafted their own version to keep spirits up."

Measures 8.5 inches tall and holds 20 oz.
