Variety created and developed by Anna Jankowski, aka "Kozula", Polish breeder. Unfixed in the process of stabilization. It is assumed that one of the parents must be "Copia". There are several different lines in terms of shape, which can vary from round to oval to flattened, and also in terms of size, which can vary from 100 to 250 grams.

The colour seems to be purple-black, with variations in speckling and speckling. Looking for more information to know if a line has been chosen to establish a standard.
