I got a Dynomighty wallet made from (basically) Tyvek house wrap. As you can see from the pic, I got the "Postcard" version, which has groovy printed postcard-y stuff all over it. As a wallet this would be somewhat useful if I was 12, but since I'm an adult with adult things like credit cards, insurance cards and (occasionally) cash that I don't want to lose, this will never be a used item.
This is the actual factual wallet I got:
And here's a link to the Dynomighty page where you can buy one of your very own. Probably won't take three weeks to get one, either.
