I got these luggage tags for my son's instrument cases (clarinet & violin).  I thought the bright colors would make it easy for him to recognize the cases without always needing to check the name, etc. They look great, but have a very strong smell right out of the package.  I have them airing out outside all day, which has had little effect so far.  If the smell doesn't improve in the next day or two, I'll be forced to send them back.  Whatever they're off-gassing can't possible be good for my kid to be breathing in, plus the smell itself is horrid.
