At Mardi Gras I drank a cask and caused all kinds of fuss. But I wore a flashing mask so I remained anonymous. To activate your Flashing Mardi Gras Mask, press the button on top of the glasses. Set the mask on 2 different flashing functions or a still light. Size: One size fits most. There is an adjustable elastic band to customize the best fit. LED Colors: 2 Blue, 2 Jade, 2 Gold Mardi Gras Face Masks include 3 AG13 Batteries. Packaging: Retail ready, individual poly bags, 12 pieces per inner box – 96 pieces per carton.
