These are Black Badge Attachment Clip Card Holders!
With this clip, you can take any loose paper like this business card and make it into a badge.
So now your loose card can join with your lanyard, or your badge reel in harmonious synchrony!
There is no need for a plastic name badge holder, and no need to punch a hole in your card or ID.
Now you can slip about to three cards into this attachment.
It works great with a variety of badge reel and lanyard attachments to hold your ID or other card.
