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.
