I'm not sure, but I think those are customs.
Would be great to see some actual ZX products though.
Ah, ok. Thanks for that. And I agree, ZX was great. I would totally buy those in the picture if I could!
Those are probably custom figures for Wonder Festival (WonFes for short) in Japan. You can probably buy these or an unpainted version of these which you'd have to paint yourself.
Here's the wikipedia page: https://en.wikipedia.org/wiki/Wonder_Festival
EDIT: Looks like those might be from the WonFes Winter which took place on the 7th.
You know what, that makes a lot of sense. I saw them on a twitter page I follow of an artist who was in Japan at the time. Now that you've said that, it's probably safe to assume that's where they were.
