Have been looking for a strong, visible, and relatively inexpensive substitute for various luggage-manufacturers' rather weak tags for sometime, now.  I like these because the rings are strong, yet can be easily removed by yourself or an airport employee (if the bag is lost).  Four stars because if you're a frequent traveler, you need more tags to write on.  Even for a round trip you need to write on one side for your destination, and one side for your return.  BlueCosto isn't the only tag-maker that seems to forget this fact.
