    Great value
    Color: Brick Brown6226, Material Type: Leather
    This wallet is a lot less expensive than similar products. It has a minimalist size. Plenty of room for cards, but you have to dig a little. I am pleased with the quality.

    Amazing Wallet!
    This is a great wallet. I searched through many styles with similar features, but most did not have the pull down side lever to lift the cards. That feature is exactly why I chose this one. The leather feels high quality and not cheap at all. It is very durable. The money clip is extremely tight and holds cash securely with no risk of anything slipping out. I also wanted a wallet that still opens to display a driver’s license and daily use cards while remaining slim, and this one checks every box. It is compact but holds a surprising amount. My husband absolutely loves it and he is very picky about wallets. There are multiple slots not only for cards but also for holding papers or notes. There is even an additional slot behind the money clip for extra storage. The pull down button smoothly lifts all the cards at once and fans them out so each card is visible and easy to grab. I was unsure how this mechanism would work at first, but the cards are slightly staggered just enough to clearly see each one. You simply grab the card you want and push the stack back down into the wallet. We chose the carbon black version and it is sleek, lightweight, and looks very sharp. My husband mentioned it needs a little breaking in due to the quality construction, but it is still easy to access everything he needs and stays compact, which was most important to him. It also comes in a very nice black gift box with fitted foam that securely holds the wallet, making it perfect for gifting or safe storage before use. I highly recommend this wallet. For the price, it cannot be beaten. I searched extensively for the best option at a fair price point, and this one easily compares to wallets that cost close to or even over $100.
