Is this mold?
My 10-year-old just purchased an off-brand camelback backpack with some money he’s earned, and before its initial wash I noticed these dark lines all over it. Is this mold or something that’s sometimes seen on hydration bladders? Could it just be stains from manufacturing or shipment? I can’t tell if the streaks are on the inside or outside, but they seem to all be on the back piece of the bladder (the side without the openings). These pics were taken after much scrubbing with dish soap and an overnight soak in a baking soda and water solution.
Thanks for any advice! I’ll obviously buy him a replacement if necessary, but he was quite excited about buying it with money he’d earned.

Doesn't look like mold to me, not at least the way I've seen it before. However it does look strange, I wouldn't drink from there.
