I've had seams split on them so at the very least, put them in gallon size zip lock bags. They're low pressure so the bag won't tear if one lets loose. If you put them in a seal a meal type bag, customs will likely cut them open to see what they are. Also put them in your check-in luggage, not your carry-on. Our's have been checked and were always let thru as long as the original factory wrapping is intact. Don't bring on an open can.
We've tried them all and they're all great!!! Orange, Caramel and Vanilla are our favorites!! (At least mine cause the "bride" is usually the recipient anyway)! LOL
Orange sounds good. I had chocolate and raspberry and well maybe they didn't go well with sambuca. It what was underneath that was way more fun.
