More stable than Crossboule

Nice design seem more stable than that of cross-Boule (we also). In Crossboccia is the stuff a little thicker and appears durable, and they are also some "plumper" filled (where these balls are not filled to the brim, but the Crossboule are still somewhat "labbe Riger") and therefore rolls even a tiny bit more - where of course what is quite different from the right Boule because when Crossboccia the balls simply - Patsch - to lie when you throw in a high arc.
Fun to play, great also in the apartment. Especially funny wirs found on the steps of an open staircase.
