Professional Look, Good Adhesive
We use these name badges often for our various career fairs. I have printed graphics on them, as well as our logo and a border. They look clean, are easy to peel (you can even peel the surrounding portion off ahead of time to make them really easy to separate for a large group), and have good adhesive. I like that they not only have perforations, but also have a red line over the perforation so you know where to separate (I prefer to cut them, as it's much quicker, so I find the mark super helpful).
