New pistons or send em' back in?

Just picked up some calipers, I have no idea if or how long they were sitting, but one was locked up so I pulled both apart to be safe. Can I send these back in or should I be ordering some new ones? Should I do the seals too? I can't see any major damage but I have no idea what the quality requirements are like for brakes and I'd rather not find out on the road.

Clean the inside of the calipers, change the seals, good to go.

They look alright, but it's kinda hard to judge from photos.
