Has anyone seen any style of Matryoshka Dolls in the parks for sale? They are also known as Russian nesting dolls. Here is a set of "Brave" dolls from the Disney Store site. I'm not in love with these at all, just using them as an example.
Pretty sure I saw these on my last visit to the Disney Store, but I've never seen any other styles out there. I'd imagine its just a unique thing for the launch of Brave, but maybe they'll continue someday if they are particularly popular.
There are some Disney nesting dolls on eBay, but most of them appear to be handmade rather than licensed products.
