Green : tyvek wristbands Our 1″ tyvek wristbands are 1″ wide by 10″ long. They are all consecutively numbered and stick using an extremely strong adhesive. Like all of our tyvek bands, they contain tamper-shredding slits, which make it impossible to remove from one wrist and re-stick onto another. The Tyvek material used is extremely strong, non-stretch or tear, and is completely waterproof.
