A buddy of mine has a company called
Wristband Express. It's pretty awesome. If you need
custom Tyvek wristbands for your bar/band/event you should check it out. There's a kick ass online designer where you can upload your logo or enter text and they'll print the design on the wristbands and ship them out. He manufactures them here so it's good for our economy and his prices are the best out there.
