The Louis Vuitton Brazza Wallet has the most card slots. This wallet is on the heavier side. It is a little thicker and taller than most slim wallets and cardholders. It is better for your back pocket or jacket pocket.
The wallet can hold up to 16 cards. Some may think these are too many, but not for the businessman. This wallet is ideal for people who travel and work. The multiple slots allow you to carry multiple business cards.
This can help with networking. Additionally, you can carry multiple credit cards for paperless transactions.
