There have been many exercises in paring down the wallet to the ultimate minimalistic design, but I believe London-based Taiwanese designer Chieh Ting Huang has arrived at that ideal quite successfully.
Nothing Fancy is a collection of non-stitched minimalist solutions for the wallet, re-imagined for the contemporary lifestyle. Using only a foldable leather hide template and rubber bands and eliminating everything else (stitches, snaps, zippers, etc.), Chieh delivers a wallet, a coin case, an iPhone holder and a passport holder within the same principles.
The result is a well thought, beautifully executed and impeccably styled range of products that has left the design blogosphere wishing for one of their own. My personal favorite is the passport holder and I'm especially in love with the customized rubber bands!
