Light Up Sequin Fedora Hats with Skulls are crazy cool party favors for rock star events. Similar to our original style fedora hat, Skull Sequin Hats are accented with a skull & crossbones patch for a more rockin' audience - modern & hip at pirate parties, plus perfect for Halloween! Skull & Crossbones Fedora Sequin Hats with Flashing LEDs really do rock & roll all night and party every day - these LEDs are long lasting! To activate, find the battery house up inside the hat & press the button again & again for all light options: flash, blink, steady lights, then off. One size fits most. 3 AG13 batteries are included and replaceable.
