I think those pink balls will contain mysterious toys that could be from Hirogaru Sky. They have an total of 5 balls with the names of the Cures down of the ball, This will probably on sale on May. I'm so excited that there're 4 days for see the official designs and i'm so happy that i've found a new Hirogaru Sky leak. I don't know this is a another merchandise or just a visual. Big thanks to yuuri_curegrace for the leak!
