has anyone else encountered this? for context, it’s lived in its little shelf nice and safe from the elements of the world only taken out for light play over carpet (i’ve tried wiping them off already lol)

i swear these weren’t here when i had ordered directly from jakes website unless my memory is failing me

question is: any of you fellow users encounter something similar?

Reach out to jake. That looks like pitting, and if so it might be an issue with the clear ano.

Old YYFs used to do this pretty commonly. My Genesis has some black spots.

I am going to guess it’s from poor ano prep.
