I ordered from Rescue Reflectors by letter, but you probably need to contact by phone to meet your timeline. I have talked to Malcolm Murray and you could not find a nicer guy. I have his #4 plastic and #21 Glass mirrors. Both are excellent.

I do not know for certain about flying with LifeBoats in your check luggage. Hopefully someone else may be able to assist on this question. These rules seem to change fast. You may want to contact the air carrier directly and ask about flying with matches in the luggage.
