I have No idea, never heard of those before. I receive my items from leftover estate sales, so don't know much about them. The small elephant has Made in Japan stamped on it. The blue deer with the glued ears has Taormina? Written on it. The others have No markings. The two birds & the turtle are pretty heavy for their size even though hollow. The birds look as if hand made, some type of clay maybe? Sorry not much help :) Fanned!
