Happy Face Tyvek3/4" x 10" You just can't beat a Happy Face to make your day as well as offering 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. In the event that someone attempts to peel back the end and apply it to another person, the adhesive holds aggressively to the Tyvek material and the tamper proof slits shred apart, making reuse or transfer almost impossible. This makes for a happy day for you and those at your party. 1 Quantity = 500 Wristbands. Questions? Please call 253 841 4057. We appreciate your business.
