Each card holder can hold approximately 10 business cards. While this may not seem like much, promotional business card holders can be effective branding on their own. These are not something you pull out for every person you pass on the street. When you give someone a card from your business card holder, it is because you believe they are a valuable person to have in contact. This type of promotional merchandise is a great way to impress colleagues, investors, and valuable clients. It allows you to offer them a card that is in pristine condition. This is also why custom business card holders are such popular gifts for your company’s sales representatives and others who will be representing your company regularly.
