I didn’t realise that Kimber was owned by Aibei. I’ve actually just ordered an Aibei doll and if her skin feels like a Kimber, then I will be extremely pleased
Kimber are not actually
owned by Aibei; rather, Kimber are their own organisation and do the specification and possibly some minor points of the design; however, they
subcontract the manufacture to Aibei in the same way that Game Lady subcontract theirs to Zelex.
Aibei is to dolls what Clevo is to laptop computers or TSMC is to microchips; half the world's laptop computers are made by Clevo with another badge then put on the case (Sager, Schenker, System76, BTO, XNB, Eurocom, Origin, and Digital Storm are the main ones) and many many microchips are designed by their owner but fabricated by TSMC (AMD branded chips in particular, my Dell workstation has one).
After starting out doing nothing but subcontracting, Aibei started selling their own designs as well and the 158 G "blonde honey" type doll is what Kimber is derived from; you can still buy this AibeiGirl now.

I don't know if the TPE mix is the same; it might be that Kimber had their own TPE blend made for them or maybe it's just one that Aibei doesn't use that often, but it does feel different to regular WM TPE for sure.
