First, let’s start with Tyvek. Tyvek is a brand of flashspun, high-density polyethylene fibers (which are a synthetic material that’s a lot like paper, but it’s also water and tear resistant). We recommend Tyvek wristbands for single-use events so you can designate access levels. We have a wide variety of in-stock colors and patterns, or you can print a full color design on our patent pending (!!!) Easy Stick tapered wristbands.
