You can store two cards or passes in the Durable pushbox duo card holder. The holder has separate spaces to provide optimal protection for both cards. This is especially useful with RFID and encrypted cards. The clear plastic makes information clearly visible and easy to read. The guides allow you to remove cards individually from the holder. The holder is suitable for both portrait and landscape documents and has internal dimensions of 87mm x 54mm. A black textile cord is attached to the card holder for two cards. This way you can wear the card holder around your neck and always keep it within reach. This pack contains 10 card holders.
