Personally I would wrap them up really well and put them in their own pocket on your checked baggage. The reason I say this is because I have had one break all over my clothes b4 and its heck to get out. Something inside my suitcase punctured it and it was not fun washing it out. We are packing ours in w/ our box we are mailing ahead of time. I would wrather it get all over something in plastic than my wallet, keys, etc.
