These are tough, waterproof, non-tear, non-stretch solid wristbands available in a variety of colors. The tape covering the glue strip remains attached to the band, so there is no litter or waste at the point of application. All wristbands are consecutively numbered. They come with a very strong adhesive and have tamperproof slits making them impossible to remove in one piece for transferring to another person. These Tyvek wristbands are 10" long and 3/4" wide.
