Does the Volks LA Sumika have Full Choice?

They do offer the FCS at the USA store, but there are some molds that are japan-volks only molds and can't be ordered at the US store.

 

Molds marked "Sato only" in FCS sites such as Angelden's wonderful site can only be ordered at the Tenshi no Sato store in Kyoto.

Other molds should be available in the LA store.

 

I suggest you call them; they are very friendly and can answer all your questions.
Here is the URL to the shop: http://www.volksusa.com/info.html
You can see the picture of where they do the FSC right there.
They do have specials on rare occasions, where certain molds are only available there and not even in Japan. If I recall correctly, the elf type molds and the sunlight skin where available there before in Japan!

 

It is true that for certain periods, sunlight skin has been available at the Sumika in LA. And yes, the three SD elf heads were available there first before also being released in Japan as Sato-only sculpts. However, sunlight was available in Japan first, for quite a few years before it was offered for a limited time in LA.
