Custom Promotional business card holders come in a variety of designs. There are two major styles:
Desktop style: Like the name suggests, the desktop style is designed to sit on the surface of a desk or table. Desktop custom business card holders come in numerous designs, and some even serve dual functions. They may have built in clocks or pen holders, for example. Desktop holders make a convenient way to keep business cards close at hand for quick referencing while you're working.
Pocket/wallet style: These kinds of promo custom business card holders are designed to be carried around in a pocket, bag or briefcase just like your wallet or cell phone. They may actually resemble a small wallet, and can be made from anything from vinyl to leather to chrome.
Choose your style with your target customer in mind. And remember, because promotional business card holders come in so many different designs and materials, you'll find a product in every price range, meaning you'll always find one that fits into your advertising budget.
