To send items that are both fragile and expensive, (such as these items), get a sturdy small box that will fit the dentures with some room for either some plastic bubblewrap, or foam peanuts for safety against chipping or breaking. Wrap the lower and upper teeth separately in a baggie, and make sure they are not hitting each other in the box. Put in your packing material around each item and ship, marked fragile, first class....(Also, you might insure them for the cost your brother paid to insure that if they are broken, he can recover his money) :-D :-D :-D
