PREMIUM GRADE TYVEK MATERIAL -100% Waterproof and durable. Stays on even if it gets wet. Does not stretch or tear. One Size Fits All - 3/4" Wide x 10" Long.JUST SAY "NO" TO GENERIC/NO-NAME WRISTBANDS -Generic/No-name wristbands often do not match the images or description. Generic/No-name wristbands are a security risk since they are readily available to any gatecrasher in most retail stores. See image #2. Generic wristbands also have inconsistent Tyvek quality, printing quality, and adhesive quality.EVENT-GRADE ADHESIVE - Goldistock wristbands use event-grade adhesive. Event-Grade Adhesive allows for easy application to the guest, BUT the security strip will tear when someone attempts to transfer the wristband to a gatecrasher. SECURITY TIP #1 - Constantly rotate the color of wristbands you use. Goldistock offers a huge selection of colors to rotate- 22 Select Series colors and 16 Original Series colors.SECURITY TIP #2- Specialty wristbands like "VIP", "General Admission", and "Happy Face" offer even better security than plain color wristbands, and are easily visible even from a distance.TYVEK-Tyvek is composed of high-density polyethylene fibers that are woven together.
