Business card cases are designed to hold and protect business cards. When you’re networking at a conference or dropping your card into a ‘win a free lunch’ basket at your favorite restaurant, your business cards are one of the outward-facing aspects of your profession. Since business cards are made of paper, it’s easy for them to get tarnished, dirty, or worn. To present a great first impression when holding out a business card to a new connection, use a business card case.
