These are small flocked ponies that come with issues of the German girl’s horse magazine Lissy. They are very similar to the Filly line, the most noticeable difference being the eye design. (Lissy offered Filly products at one time, and appears to have created Magic Ponys after their partnership with Filly ended.)
I have found at least two assortments that were sold independently in blind boxes. These are distributed by Blue Ocean.
