Description The PROOF Apex is a slim RFID-blocking wallet built on an aerospace-grade aluminum frame wrapped in matte black full-grain leather, finished in satin gunmetal. It holds up to 25 cards inside the frame and 20 folded bills under the rear strap, at 1.75 oz. How It Carries Cards sit inside the aluminum frame rather than in leather pockets, so the plate takes the pressure instead of the card edges and protects them from bending. RFID-blocking material is built into the interior. A leather pull tab on the front fans the stack out in one motion. An elastic strap across the back holds folded bills flat against the plate. Full-Grain Leather Full-grain keeps the outermost layer of the hide intact rather than sanding it smooth. It is the densest part of the skin, it takes a scuff without losing the surface, and it darkens as it ages. Satin Gunmetal A brushed, brighter finish on the aluminum plate against matte black leather. The metal is cut, sanded and finished with rounded corners, so the wallet moves in and out of a front pocket without catching. Designed by a team of U.S. military veterans and engineers. Protected by U.S. Patent No. 12,604,959 and U.S. Design Patent Nos. D1,138,157 & D1,138,158. Covered by PROOF's lifetime warranty: if you damage or lose the wallet, PROOF replaces it.
