This is a NUVO plastic wind instrument, the jHorn, in Bb/C key. Black/Black N610JHBBK (with dedicated semi-hard case) I purchased this about 5 years ago and tried it out a bit before putting it away on a shelf. I am now selling it to organize my belongings. The jHorn is a plastic wind instrument, and its sound is similar to a horn or euphonium. Beginner musicians, why not consider purchasing this?
