Bought these as a joke, but they've been really handy. Since 9/11 our work has required the use of ID badges. It's always been easy to misplace the badge, so I bought these for that also. They are holding up well and I've shared all but two of these and everyone loves em. My only complaint is the shipping cost (primary reason for 4 stars instead of 5) and that is why I ordered an additional set, to defer the shipping cost over 14 items instead of 7. I'm not sure how many sets you could buy before freight costs go up, but It would be worth finding out if you can use them. All in all a good quality product and you can "smile" even if you're not in the mood.
