You may be thinking of something on the line of Nalgene labware. That stuff
is mega sturdy, but pretty pricey.

A specimen cup has a larger diameter and volume (100-125 ml) than a 50 ml
centrifuge tube and costs less than a Nalgene jar.

OK, just had to get that "desiccant" spelling right-- two "C"s and one "S".
Sorry, folks, it's on the frequently misspelled words list, along with
"misspelled" and I have a spelling-bee-er in my household! Now, with that
out of the way, I have to say I really don't like those Rubbermaid
containers. I've found about 2 dry ones in 6 months of letterboxing, and
many with chewed holes. They're just too thin and don't seal well. I
remember someone listing a website on here, maybe 3-5 months ago, with some
kind of science tubes or earth tubes or geo-tubes or something to that
effect. They were made for being outside. I think they were thicker plastic,
maybe w/ screw-on lids? And were bigger in diameter than centrifuge tubes
you're describing. Maybe I dreamed the whole thing as my ideal letterbox. I
saved the post... will see if I can find it & keep you
posted! --lunaryakketyact
