On our last cruise, one of my wife’s luggage bags wasn’t delivered along with the others. I asked her if there was anything in it that might be prohibited 🙂. The reply was “no”. Long story short, she’d packed a heating pad and it got confiscated. We were on a B2B cruise and after the first cruise ended we saw it, along with the other confiscated heating pads, set out on a table, for the departing cruisers, (we were debarking along with the other B2B cruisers to go to Customs and immediately re-board). When our second cruise ended, she went to claim her’s and it was no where to be seen / found. I hopes this helps someone in the future so they won’t experience what my DW did.
