>>6317155>>6317101BJDs work differently than other doll collecting communities because we don't exactly do this whole "finished customs for sale" thing.
Reasons below:
1): people who buy BJDs do so to customize them to their liking, often with the idea of representing an OC.
They don't buy them already finished because the whole fun is to customize a blank slate into your vision and/or because it's very unlikely to find a doll that already looks like your OC.
Among fashion dolls it's more common to buy/offer finished customs because the actual "collecting" urge is stronger.
I honestly wouldn't call most BJD owners collectors because most of them don't really collect by definition.
2): Most BJDs are just painted.
Unlike MHs, Tonner and co. you do not need to remove some ugly paintjob/print and then do some magic on the face.
Unlike Blythe you do not need to carve the fuck out of the face till it goes from flat alien to something with depth (since Blythe face-ups are usually very bland, it's all in the carving).
You usually just need to paint BJDs, the rest is already there. No re-roots, carving etc.
3): BJDs are very expensive, and the margin you can make as an artist is usually small.
You can get some Blythe for 150$ and sell it for 1000$, but the nice looking BJDs that sell well are already close to 600-800$.
Add a) and b), and barely anyone will risk buying a super expensive doll, customizing it and not getting it sold.
In short:
BJDs are intended as blank dolls, finished by you.
Company full-sets are either for photos only or sold in limited quantities.
Companies do offer at least to buy the face painted on already.
Most dolls you will see are customized by their owners/artists they commissioned to customize their doll; they are not for sale like that anywhere.
The most you can get is someone selling their doll with a face-up already on the face, but you still need to dress it, buy a wig, eyes etc. yourself.
