Almost every single time I pull out this wallet I'm asked about it.  People of all ages are intrigued by it and think it's cool.

If you're looking for an very thin wallet, this is a great choice.  It adds virtually no bulk.  It doesn't include a lot of room for cards, which is fine for me because I like to keep my cards in a separate card holder and use this wallet solely as a billfold.  I can put it in a pocket and there's no bulge.  The bill compartment is divided in two, which I find handy.

I've had it for a few months and it doesn't show any wear.  Because it is made of Tyvek, it's subject to being pushed out of shape by your pocket.  I haven't found it's much out of shape, but it is a little bit.  And I'm sure it will wear fairly quickly.  I bought it as a novelty, assuming it will be good for a year or two.

All in all, a good choice if you're looking for an interesting, thin billfold and don't have unreasonable expectations about the ability of Tyvek to hold up to wear.
