You’re referring to the Violette and Hortense dolls right?
I’m not entirely sure. I don’t really keep up with that sort of news, but I am under the impression that the dolls were a limited run, as most Sound Horizon merchandise is. You can probably find the dolls for sale by individuals on sites like ebay, although they will likely run a very high price. I don’t believe the dolls were sold in a pair either, so it might be hard to track them down down.
I’m sorry I can’t be of more help! Do any of my followers know anything more about the Hortense and Violette Pullip dolls?
