Our self stick business card holders are a great addition to any of our Stack Displays! They can even be added to our brochure holders, too! They can be applied to just about anything with a smooth surface. Each business card holder will hold approximately 30-50 business cards, depending upon the thickness of your business cards. Each card holder comes with a thick foam "peel and stick" adhesive. Just peel the tape and apply the business card holder anywhere on your display! It's a great way to ensure that your customers always have the option of taking one of your business cards with them! Business card holders are always in stock and ready to ship!
