Originally liked the concept of hiding name/address, etc. and the appearance but after using these tags on a few trips I realize that the little airplane cut-out must get caught on things because these tags are getting mangled between drop off and recovery at the airports.  Or they're simply too large for what is actually needed.  At least they're pliable because the last trip to Mexico had them looking pretty poor almost bent to a 45 degree angle!.  Straightened out but they'll never be the same flat style again.
