If pro refers to all products of bull then there is no strict sense of propaganda! Because Bull started his business with a concept: \"Loyal and sincere, professional focus\" this is not a propaganda but now if you are talking about the wall switch socket, there are indeed similar propaganda words should be \"let the wall a little more color\" this sentence because the bulls in addition to the basic model are mostly colorful panels When the Rubik's cube color panel was launched, there was basically no big brand in the market with such a fancy wall socket switch! As for the material and process I will not mention more only for your reference!
