heat transfer wristbands, our dye sublimation wristbands are a simple item for your event. Your custom design can be produced to any full-color specification into the polyester band. The one way sliding barrel lock uses prongs to pierce fabric, prohibiting the wristband from being transferred. Great for use at concerts, festivals and amusement parks, serving as highly visible, non-transferable tickets that are worn by attendees and paid guests.
