If you appreciate the morbid and awesome, then the glass skull drinking cup is the right choice for you. This cup doesn’t merely display a little picture of skull that’s supposed to be scary, it fully commits by actually taking the form of a human skull. Each skull glass measures 4″ x 4″ and has the capacity to hold up to 16 ounces of your favorite rum drink. When filled with booze, it’s guaranteed to get you inebriated faster than you can lift the sails and ready the cannons. Also, even though the glass skull drinking cup resembles the ghastly Skull Island (a notorious pirate haven) it also works great during Halloween as a spooky but useful decoration.
