This is a Nikkan-made tenor recorder, "Superio Tenor Pipe Nikkan." The tenor recorder is a type of recorder, a woodwind instrument, that is larger than soprano or alto recorders and produces lower-pitched sounds. Nikkan was a Japanese musical instrument manufacturer that was later acquired by Yamaha Corporation. Tenor recorders are used in various musical settings, such as solo performances, ensembles, and educational environments. While I believe maintenance is needed, it still produces a beautiful tone. Sound has been confirmed. The movement of the metal parts is slightly sluggish. There are some dullness and dirt. Please check the condition in the images as this is a used item. I believe it is still in a condition that allows for reuse. The case has damage and the metal has rust. I am not very knowledgeable, so there may be differences in the comments, so please ask any questions. I will answer as much as possible. I am careful with packaging. I will wrap it in air cushion and ship it in a cardboard box.
