I see a lot of wallets when I am looking for things to write about here at the Gadgeteer, I have even been fortunate enough to review a few. So, in order for me to write about another wallet it needs to have an interesting design or feature. The Billetus Carbon fiber Billet wallet, a Kickstarter project by Dennis Kaping, has done that. The Billetus comes in two versions, the Maximus and the Minimus. Although the Maximus version is the one that caught my eye, I will mention the Minimus also. The Billetus Minimus is a 601 aircraft grade aluminum unibody frame that is designed to hold up to five cards and five bills with an elastic band keeping them in place. With outside dimensions of 2.65″ x 3.85″ x .365″, it is not overly thick. Built using a Carbon fiber exoskeleton, an aluminum frame and face plate, Titanium fasteners, aluminum washers and a Carbon fiber clip, the Billetus Maximus is the Rolls Royce of this collection. All of these parts integrate allowing the Carbon fiber clip to keep tension on the aluminum face plate keeping your cards and money secure within the exoskeleton and frame. With dimensions of 3.09″ x 4.05″ x .375″, the Maximus can hold up to eight cards and five bills comfortably. There are many pledge points for the Billetus with a $45 pledge getting you a Billetus Minimus and two elastic bands. A pledge of $105 will get you a Billetus Maximus. This project is seeking funding until October 23, 2014 and if successfully funded will start shipping the Billetus in the November 2014 time frame.
