Our Vertical Secure Zip Badge Holder is made of durable vinyl, has 4 holes at the very top for easy pin attachment, and a center slat for attaching a bull dog clip or swivel thumb hook with lanyard. It holds a 2-3/4" x 3-1/2" card.  This badge is purposefully produced to clearly see-through the badge for identification, also to secure your badge or event tickets safety in place. This is ideal for business conventions, expos, meetings, sports events, concerts, military, trade shows, businesses, schools, and general use purposes.
