According to the United States Postal Service website, it’s illegal to send body parts through the mail.

“Heavily restricted,” is a better way to put it. You need the necessary permits, containers, a transport license from the American Association of Mortuary Shippers. There are rules involved, special restrictions; same goes for dry ice and lithium batteries. You can mail live bees, but not medical marijuana. Those thin, translucent lines that keep us from stuffing a toe into a manila envelope on the way to work.
