Abyss (Money Clip Wallet) The Abyss has been completely designed in house at El Diablo Leather. Featuring external slots for over twelve cards as well as a stainless-steel money clip for folded notes, the Abyss will not disappoint. The Abyss is available in our full range of Italian Pueblo/Buttero or Australian made Crazy Horse leathers in combination with our complete line up of Ritza Tiger thread options. Crazy Horse is the recommended leather for this design, as it is a little thicker and firmer. That being said, our Italian leathers will be a good choice for those after a more slimline yet vibrant wallet.
