Clear vinyl heavy-duty prox card badge holders are perfect for wearing access cards on a clip or lanyard. User may slide the card in and out via the opening at the top, then seal the holder by attaching a clip or lanyard. Cards stay put until the user opens the top by removing the clip or lanyard. Portrait orientation badge holder features .020″ thickness front layer, with a .030″ thick back layer. Anti-print transfer material prevents image printed on card from transferring off the card surface and onto the card holder.
