▲ Those aren't from Yujin. They are made of resin (not PVC) and come as unpainted kits that need to be assembled and painted by the buyer (or a modeler he comissions). I'm getting that Suiseiseki one; last I heard my kit will coming in with the next shipment. Hopefully I'll be able to get the completed product by end of Jan.
This
one is from Yujin.
They can still be
procured. Even the Yujin Souseiseki.
