The Aviator Wallet
As you can see from that demonstration, getting cards in and out of the wallet is quite easy, thanks to both the integrated thumb window and adjustable elastic band that can comfortably hold up to 20 cards.
You can use that same band to hold bills, or if you prefer, you can add an optional 3D-printed cash clip to your order for an extra $25. Another optional add-on item is the coin tray seen in the video, which comes in handy for keys and SD cards as well as it does coins.
Their best-sellers are the silver anodized aluminum (~$69 USD) and black carbon fiber (~$115 USD) editions, but they do have a number of other options to choose from as well, including the high-end Titan One Rugged ($343), made from 99%-pure Grade 1 Titanium.
