Yep, I have one of these which I combine with the Titan Kettle for ultralight trips; the cup fits inside the kettle & I can also fit my Optimus Crux (folding) stove + lighter + sponge + small tea towel inside - a complete little meal kit
The cup is 400ml & the kettle 800ml.
The cup is only single walled & hot liquids tend to cool pretty quickly, especially in cold / alpine conditions.
I also have a double walled cup for more luxurious trips
I definitely did not pay the Aus retail price, I think around AU$60!!!
I think over the net I got it for less than half this a couple of years back.
Cheers.
