Tyvek Wristbands3/4" x 10" The tyvek wristbands are our most popular item. They are low cost security for your event. Each wristband has tamper proof slits, backed by an aggressive adhesive, and come pre-numbered for excellent inventory control. These wristbands will fit a large person, or a small child. Simply remove the covering from the adhesive, wrap it around the wrist, and adhere it onto itself.If someone tries to peel it back in an attempt to apply it to another person, the adhesive holds and the tamper proof slits shred apart making reuse almost impossible. 1 Quantity = 500 Wristbands.
