Is the best way to send them. Try to package them so they stay seperated in the envelope. As for 2 of the same chip, since you are sending them to Paul Donohue, he has every chip known to mankind so it wont matter. But seriously, if possible, it should be two different chips that you send. Of course if you only have one kind of chip (like Jill B and Bucky's when she started and look how far she has come) then send those.
