Fit the Norwegian tags well so they didn't get torn off, you might have to trim a little inside the lines but not much.  Other folks asked us where we got them.  There are also 2 lanyards to use for the cruise cards.  Would recommend these to anyone going on a cruise.  Keeps your tags on your luggage and gives you a nice thing to keep your card with you on the ship when you don't want to lug around a backpack or purse. The price is good too.
