These tags are made of tough plastic with a rubber-like strap that snaps close to attach it to your luggabe handle. All you do is take off the strap, swivel the top around, put your name etc on the card- making sure your name appears in the window (I printed off our names and address on white printer paper, using small font and it fit perfectly and is very readable. I also put a piece of clear packing tape over the paper in case the little plastic window cracks) It's nice to have just our names visible instead of all our information. Then swivel it back around, put the strap back on and you're all set to go. Highly recommended.
