These overlays are brand new and come on as peel and stick labels you apply manually. It is very easy to apply if you take your time. Each measures 2.05 in. x 3.3 in. (52 x 84 mm). This is larger than a standard ID card size. This makes it easy to position on the card and then trim away excess with an X-Acto knife. These are only .05 mm thick so you barely know they are there! You can place these overlays on almost any ID card, including the inkjet PVC cards we sell. Works on Zebra, DataCard, Fargo, Evolis, Magicard, NBS, etc and more! They also add some protection to the actual ID card in terms of damage as well as security.
