This is a clear plastic business card holder that can be attached to any of your plastic boxes. This pocket is bonded to our plastic boxes so it must be ordered when purchasing box(es). We have a different item to attach to a cardboard box. We add business card holder to bottom front of box. Please email us at firstname.lastname@example.org if you would like holder on different location. If you already have boxes or displays and want to add a business card pocket please select the business card pocket with back.
