This is no longer for sale.
It's used, but still works great. I made a much larger one, and really have no need for this one anymore.
This keeps your collection containers from tumbling all around, and keeps a stable temperature, even in fairly extreme conditions. It also keeps a high humidity because of the water tanks in the bottom.
You can read more about it on the thread I made for it here (http://www.formicult...rage-container/).
Comes with everything here.
The smaller collection containers are actually brand new. They've been cleaned out, and I've been using the same containers for a while now, and haven't had any problems with them harming the ants I put in them.
There is also Hydrostone in the bottoms of all the collection containers. This keeps them humid and gives the queen ant or whatever is in them a source of water. It also allows them to survive for a few days in case you don't have the time to move them to test tubes or some other container right away when you get home.
