If pirates had freezers and a penchant for cold drinks, this is the ice cube tray they would use. You get a 4-1/2" x 8-1/4" silicone rubber ice cube tray that makes 8 ice cubes at a time, 4 skulls and 4 crossbones. If you get creative with the colors of the liquid you use to make ice, you can do some really cool stuff. Who doesn't want a purple skull keeping their lemonade cold?
