During his daily performances, Bonna was fed up with the weight of his horn case, which was always a hassle when traveling, and he wondered, "Isn't there a way to make it easier and safer to carry the horn?" "I want more people to be able to enjoy the horn, an instrument I love, by being freed from unnecessary worries!"
