Best place to buy small amounts of Tyvek wristbands for bags?

  1. Can anyone recommend a good seller on eBay or elsewhere? I was hoping to buy 50 but I suppose I could buy 100 if I had to. Thanks all!
     
  2. Party City sells them in amounts of 50
     
  3. Thanks!
     
  4. ^ but can't those little strings just be untied and retied?
