Just an update and a caution...

#2, #3 and #4 made it to their first destinations and are already
moving toward their second stops. However, #3 arrived in damaged
condition and had to be repackaged. Please feel free to repackage
these postal travellers however seems prudent, when you send them
on. Apparently two of the containers were not as sturdy as I thought.

So far, #1 has yet to arrive at the first destination, so that is
worrisome. If it fails to arrive after another week, I will recarve
the stamp and make a new letterbox 'ensemble' and start it on the
journey again.
