This is a mug shaped like a stalk of bamboo and encircled with rope and a ring of skulls around the base.

It has dark vertical streaks of "weathering".

There were two other differently glazed versions manufactured by PopTiki for Kahuna Kevin, who is the author of several published cocktail books, including 'Why Is The Rum Gone? Volume 1' and 'Why Is The Rum Gone Volume 2'. There was the Aged Brown glaze version and there was also a Fresh Cut Green version. Each came with a braided jute rope bracelet decorated with "Harpy Eagle Talons" around the top of the mug. Each also came with a special drink card for the original "Voodoo Bamboo" cocktail made with unusual ingredients including Imperial Stout and Porto Wine.

This version appears to be a custom version or Artist Proof from the same mold but differently glazed and not from Kahuna Kevin...sold by PopTiki in 2019.
