Anyone know what type of bearing in x3 La Goutte?

The concave one in the set it comes with.

Trying to figure it out

I believe that for the US they’re shipped with a flat bearing (due to the KK patent there), I also think it’s a C-size.

Just got an email from xela.
Said it’s an abec 7 dry.
I could swear there’s some sort of coating, it spins like its dry but is dead silent and smooth as a 10 ball
