My sister & I chipped in to buy a small supply of these & we use them on all our cruises. They are very sturdy and have never come off during travel Do you use them or are you considering using them? I used to cover the tags with packing tape but now I don't have to do than anymore. I love them and recommend them. My other sister was supplied with two for a North Weztern US land trip by the airline she traveled. That was nice. Wish that the cruise lines would give them out for cruises or for perks.
