Stickers you can put on your luggage to make it easily identifiable? Good idea. Silly stickers like blocks of cocaine or dildos? Juvenile and likely to have Customs paying you more attention than you’d really want, but if you are silly enough to use them, then you deserve what you get. A sticker showing a bound and gagged female flight attendant in your luggage? Well violence against women is so edgy and politically uncorrect and cool ya know. No, actually I don’t. So you want to stand out from the crowd? Wear fluoro t-shirts or dye your hair bright purple. You don’t have to offend and potentially trigger harmful episodes in people around you to convince others that you really are a wanker. Want to be able to easily identify your luggage? A non offensive sticker, or a bit of ribbon or string tied around the handle does the same job and it’s cheap and unlikely to offend anyone or trigger them, or call undue attention from Customs.
