Do these tubes look like manufacture defect?

Just want to make sure not over reacting

Looks like they were stored for a long time wrapped up. I might try to air them up to 15-18 psi and let them sit in the sun for a half hour or so to see if they find their original shape.

Sounds like a good idea

I wouldnt run them even if they look right after some heat.I run tubes in a few of the old Harleys and if I had one like that it would go back or in the trash.Been installing tubes in car and motorcycles since the 60s.Rocky

I've seen tubes that look like that after they had been installed in a set of tires that had a fold in the tube like yours look like in your picture. They would usually smooth out after a few days when inflated up like yours are now Look very closely at yours, if the seration on the outer sides are missing in the fold DON'T use them If they are missing then I'm sure thier defective from the maker

Those are defective... period... I run tubes in my
slicks all the time... never seen that.. send them back
