The cover is made of polycarbonate hard plastic and has high heat resistance and scratch resistance.
The ID card covers with carabiner yo-yos, for two cards, are a very convenient way to attach card holders or ID card covers that serve as protection for employee badges, press passes, access cards or other proof of identity and should be quickly at hand.
When wearing card sleeves for crew passes or access cards on a clip and or yoyo, it is very convenient to be able to wear the card holders fairly close and securely on your body and still be able to have them quickly at hand.
Simply pull the card sleeve and the cord of the yoyo is released.
When you let go, the yoyo cord is then automatically re-fed cleanly and the proof of identity or the attendee pass for the event is again close and secure to the body.
