Marcus Bonna horn case. It's a Baby 2. It fits Alexander 503 and 103 horns. It can accommodate more models than the original Baby case. Used for about six months. I bought it new, but I haven't used it much, so I'm selling it. It's in very clean condition as it hasn't been taken outside. There are no smokers or pets. Everything in the photos is included. Feel free to negotiate the price. Please send me a message. Thank you.
