Product Description

3d printable sandstone testtube for shipping samples (single item) of insects, worms or even just soil (different types)...

Sandstone (https://en.wikipedia.org/wiki/Sandstone) testtubes (substitute for canisters) to save worms/insects in extreme temperatures! Worms and insects that survive at room temperature can be preserved longer with sandstone worm can compared to a metal canister! It is also rust proof (http://www.wormfarmfacts.com/Worm-Bin.html)!! It also doesnt freeze soil eliminating the need for defrosting! Testube can be sealed from top with a lid (http://shpws.me/M7Le) and screws (screws and threads not included)
