It certanly does have advantages over regular paper wallets, since its more durable,not easily destructible,etc.. and i love the design.
The first thing that crossed my mind when i saw the picture was, i must weigh a lot, but it seams that its only ~200 grams weight, which isnt much at all.
I just hope the price dosnt come too high, <50$ seams ok, but anything above is too much and people will look at other products.

cheers
