These cruise luggage tag holders (with straps) are designed specifically to hold, display and protect the e-luggage documents that are provided by most of the major cruise lines - Princess, Carnival, RCCL, Celebrity, Disney, Norwegian, NCL, etc.  They are reusable.

For individual cruisers it simplifies the embarkation process, allowing the traveler to be free of staplers and tape. These tags clearly display cruise status, cruisers name, stateroom, and ship name, on both sides - no cutting, taping or stapling, making it easy for porters to deliver luggage to the appropriate stateroom without the risk of the paper tags being ripped or torn off, meaning less lost luggage.  For Travel Agents, they make a great inexpensive bon voyage gift for clients.
