I hope the loose joints are just a one time thing.
Like I said in the review, I normally find that the CnC parts that come with the figures have very stiff joints, which may be one reason these didn't make it to retail. That's assuming of course that these aren't just pilfered parts for someone's personal gain....
Based on some of the figures I've picked up from these Chinese sellers I think they fall into a couple of categories:
- Genuine excess stock/overproduction
- Rejects
- illegal overproduction (run the machines through the night after official production finishes)
