The Durable card holder offers space for two access passes, company passes or magnetic cards. The holder is suitable for inserts with dimensions of 85mm x 54mm x 0.76mm. (0.76mm is the standard height for passes.) Removing and changing cards is quick and easy thanks to the thumb recess. This card holder is equipped with a roll-up mechanism. As soon as you pull the holder, the retractor cord stretches. This is ideal if you need to hold a card in front of a scanner. Thanks to the clip on the back, you can easily attach the retractor to your clothing. The package contains 10 duo card holders with a roll-up mechanism.
