This mug is based off a set piece in the film, Indiana Jones and the Temple of Doom (1996). At the center of the smaller side of the temple stood a large statue of Kali and an altar in the shape of a skull that housed the Sankara Stones (which glowed when activated). This mug has a natural brown stoneware finish and includes an insert glassware and glow cube to allow for inner glowing while drinking. When not used as a drinking vessel, remove the inner glass and use the Altar as a candle holder or other decorative piece. Also came with a drink recipe card.
