Tyvek wristbands are still one of the least expensive security features on the market. The USA flag pattern is one of our most popular patterns. These wristbands are made from tyvek material which is both waterproof and very strong. The aggressive adhesive holds the wristband in place. There are tamper proof slits in the material that causes the tyvek to shred when trying to peel back the end of the wristband making them non reusable and non transferable. The price is $22.00 per 500. If you have any questions, please feel free to contact us at 253 842 4057. We are happy to be of service to you.
