This is a cool wallet. My previous wallet didn't protect my cards and as a result they would get damaged. This wallet is like bullet proof and fits all of my id and credit cards perfectly. I really like the magnetic fold which is very secure, but the most comforting thing about this design is that my cards cannot be scanned. Very secure. Highly recommend Bulliant wallets!

Great front pocket wallet.

Material Type: Leather, Color: Coffee-4338

This Wallet is great. It took some getting used to having the cards all in one slot, but since they pop up in a stair-step design as long as you keep your cards in the same order you’ll always reach for the right one. Materials are high quality and it feels good in the hand. I really like the look and weight of this wallet as well. I will likely purchase these as gifts for the other men in my life.

Just received the wallet. It does exactly what I expected it to do. Hold my cards securely and has a money clip, plus rfid blocker. Great price too.
