3) THE WATERPROOF
The basic requirement is that
it be waterproof and hold the stamp and notebook comfortably.
While others have researched a
cylindrical tube from a surplus supplier, I prefer Rubbermade
containers, of which two seem to work. My favorite is a #3865
"Servin Saver - size 11", measuring 4"x7"x2" inside, nice smooth
white cover for a label.
They also make a similar size,
#5534 (size A), blue cover, more rounded sides (shown in the earlier
photo). This size will allow
the notebook (and some postcards) to lay flat inside.
Which ever you can find (try
Wal-Mart or anyplace that sells housewares) works OK; I like the
white one when I can find it. Either way, squeeze it to make sure
the seal is good - one that I bought wasn't. Cost $1.50 - $2.00.
Make a label for the cover, again,
with the Letterbox name, and where to contact you if it has been
disrupted. And, a PLEA for the finder to respect its contents.
Keep in mind, unlike Dartmoor, the odds are high that a chance
finder won't know a thing about letterboxing. Mine say:
