What's the smallest nozzle you use?

I still only have 0.4 mm nozzles. I've considered larger and different materials, but hadn't really thought about small.

How small do you go and what do you use them on?

I am also curious. Ive used .4 only so far, but i bought a nozzel kit with a bunch of sizes to eventually try.
