This auction is for 25 Cardstock postcard holders. The dimensions are 4.75" wide, 2.5" deep and 5.375" tall. They have 2 slits in the front to insert one of your own business cards. These work for displaying your cards vertically. You can hot glue, 2-way tape, or staple together. They will be shipped flat. We are the manufacturer, so ask me about volume discounts.  Check my other auctions for other styles of holders. Thanks for looking!!
