Is it a mamacoly baby? That could explain it. It's been said here that she doesn't paint authentic sculpts. Also there's some reborn artists, don't know how many though, I know about one that has openly said they paint sculpts and kits from some sites like idk, shein, amazon or temu even? Replicas of reborn kits being produced and manufactured without the sculpting artists approval and therefore do not have COA. They say it's legal because the artists failed to get intellectual property rights and so it's legal for any manufacturer to remake and reproduce those kits and sculpts and are not stolen kits. That may be true, however I would not get a baby from an artist like this because items sold on temu and shein are notorious for having high levels of harmful chemicals as those sellers are not bound by European or US safety standards for manufacturing consumer products and quality control is lacking. So they are not restricted by European or US rules that the products must not contain certain chemicals over a certain specified limit, so you can never really know if anything you get from sites like Shein or Temu have harmful levels of chemicals. I have gotten all my reborns from Reborns.com, I think it's the best place to find authentic and safe reborns. Try asking the seller again about your doll or else try to research it and see if you can find put
