This is a pack of ten business card holders. They're clear acrylic, so they look very polished and professional. They'll each hold a large number of business cards. And when you're not using them, they will stack on top of each other, saving space.I own my own small business, teaching private sewing classes. One of the local fabric stores requested a stack of my business cards to pass out to customers who ask about classes, so I gave them one of these holders along with my cards. That way, they can keep my business cards organized and right at hand, instead of having to rifle through a drawer for loose cards. I also keep one in my sewing room, so my students can take a card if they need to. It's much more professional-looking than keeping a stack of loose cards.Others have had problems with the acrylic being scratched up when the holders were shipped, but mine were shiny and beautiful when they arrived. I give them five stars and highly recommend them for anyone who wants to display their business cards, whether it's at your own desk, or at a convention booth, or when giving a stack of cards to someone else to display for you. It adds a nice touch of class and professionalism.
