How do you send a rock in the mail?
How do you send a rock in the mail? If it is heavy - a flat rate box is a good idea with cardboard and bubble wrap. If it is small, then a little box and bubble envelope. Or, you can sandwich it in cardboard, tape all around and add some bubble wrap for a bubble envelope. Not all rocks are terribly breakable, but why tempt fate- or the PO.
Can you bring rocks on a plane?
According to the TSA, you are allowed to bring rocks and minerals on a plane. You can pack them in your checked luggage or even keep them your carry-on bag. If your samples are sharp or fist-sized, it is best to put them in a checked bag to avoid the appearance of a potential security risk.
