Based on the earlier Diver Duke diving helmet mugs made for Tiki Caliente, this version has all of the face windows cut out and takes a clear glass on the inside to actually hold beverages (and a glow cube for haunting glow effect).

Drink special for the Diver Duke Mug is the “Treasure of La Amadarita” (by Brandon Glass) consisting of 1 and 1/2 oz Doctor Bird Jamaican Rum, 1 oz El Dorado 5 year rum, 1/2 oz Lemon juice, 1/2 oz Grapefruit juice, 1 oz Honey Syrup, 3/4 oz Banana Liquor, and 1/4 oz allspice pimento dram.
