Marcus Bonna horn case. It's a Baby 2. It fits Alexander 503s and 103s. It can accommodate more models than the original Baby. Used for about six months. I bought it new, but I didn't use it much, so I'm selling it. It hasn't been taken outside, so it's in very clean condition. 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.
