About 5 years ago I put over 200 matchbooks in a plastic container and placed it into my checked luggage. When I got home I found a TSA notice and my matchbooks were gone. Boy, was I burned!

Since that time I get a USPS Priority Mail Flat Rate Mailing Envelope. I also get a 8½ X 11 size #2 bubble cushioned mailer and take both on my trips. I put my newly collected matchbooks into the bubble mailer and place in into the Priority Mail envelope. I address the mailer to myself and drop it off at the Post Office counter the day before I return home. Cost is $4.60; until it goes up again in May.

I've received the matchbooks in excellent condition every time so far.

Why can't you transport matches in checked luggage but it's okay to mail it via USPS?
