Slim front pocket wallet from Recycled Firefighter. Fits 5 or 6 cards, and there's a money strap on the back for cash. Great piece, my other one has lasted for years — probably because it's made of indestructible fire hose. Regularly $40 on the company website, as you can see from the included screenshot. This has never been used.
From the maker's website: The #1 Bestseller Sergeant Wallet - Firehose Edition is our top-selling, battle-tested minimalist wallet, forged from authentic, decommissioned U.S. fire hose. This front-pocket design is rugged, slim, and honors the grit and strength of the fire service. It delivers extreme durability and essential functionality in a compact form that thousands trust for their everyday carry.
