Kevin Harrington, an original shark on "Shark Tank," explains what it means to be a minimalist, which he says means traveling light with a SERMAN BRANDS wallet. A man getting coffee at a shop with a bulky wallet fumbles with his cards. SERMAN BRANDS says most men only use one or two cards a day, which makes its slimmer minimalist wallet perfect for them. When the man gets coffee again, he's using his new wallet, which allows him to instantly access cards with a smart strap. SERMAN BRANDS believes in giving men maximum productivity without even opening their wallets.
