This doll hasn't proven to be official!
It was made in China, but sold to Japan. It was aquired without a paper tag, but the cloth tag seems normal /appropriate. The quality of the whole plush looks decent too, with good proportions (though the spikes are slightly thin) The eyes are embroidered, & there are no obvious defects or mistakes on the shoes, which is usually where bootlegs will start to go wrong. It just seems too quality over-all to be a fake, but what set or where was it from?
