The Patented dual-function STORM XL LED Wristband is the perfect item for co-branding! The wristband features a switch on the side of the clasp that transitions between a flashing light and a steady on light. With the switch on the side of the clasp, the entire face of the clasp is open for our SPECTRUM UV Full Color Printing! For all colors, the wristband is clear when the LED is turned off. Once turned on, the LED illuminates the wristband and engraved message in the color of the LED.
