The haydanhuya wallet is a beautiful addition to your daily carry. The minimalist piece is purely a labor of love by Gökhan Eryaman. Each wallet is personally addressed to you and stamped with unit number on the bottom. I bought the walnut brown leather for a hefty $85 and really couldn't be any happier with the way it looks. It lacks utility; it holds maybe eight cards and don't think I could ever sit on it but you really buy it for its simple elegance.
For those with a stockpile of cards and coins, its not the best option. If you only carry the necessities, check out this beauty at http://www.haydanhuya.com/
