Despite its thin and small nature, the slim wallet is often a canvas for surprising amounts of design creativity. Mountain Voyage's stylishly slim wooden wallet follows this tradition well, featuring two thin slabs of smooth walnut wood screwed onto separate plastic plates, which are then held together by a wide elastic band. The space between is where you can insert 10 or more cards, expanding as needed thanks to the elastic.

On the back of the wallet is a detachable carbon fiber money clip that can hold around 8 folded cash bills, and the body of the wallet has a rounded notch that lets you push out your card collection for easy access.

Get the walnut version of this wallet for $40 on Amazon. They also offer carbon fiber and aluminum versions for around $36.
