Pretty cheap, not as cheap as test tubes but still not bad at $13AUD ($10US) including 2 week EMS delivery to Australia, from Aliexpress.
They shipped it out within an hour of my order

Getting a white one. I thought this would be the most neutral colour to be able to see the ants as well as the brood, and photograph well
Funny enough, double width version is the same price, but only available as transparent.
These have a 10mm tube exit.
Advantages over test tube - a sponge hydration system, with optional use of a refillable test tube and sponge to wick water onto it for long term hydration, which shouldn't have the same mold issues as a cotton dam in a test tube.
There is a sliding lid near the exit to use as a feeding port.
Flat surface for ants to walk on.
No refraction image issues, and less reflections on the coloured versions.
This vid shows how it works
I'll update later on how it goes
