The hard case does not have a key. ●Included items Main unit, mouthpiece, hard case *Everything in the images is included. ●Product condition There are scratches, marks, and dirt. The pistons move up and down, and parts that can be removed are removable, so I don't think there is any sticking. I have not confirmed the sound production. *Please be sure to check the images.
