Thank you for looking! This was used as a prototype model for creating a handmade instrument. There are no noticeable scratches or stains. With its expressive tone, you can enjoy any ensemble you like. It's an ABS resin tenor recorder. Arched windway: By providing a certain amount of resistance when blowing, it makes breath control easier. It produces a brilliant tone. Detachable thumb rest: ABS recorders (soprano, alto, tenor) come with a detachable thumb rest. It can be attached to suit the player's hand and helps stabilize the recorder. (The bass recorder's thumb rest is fixed.) Eco-friendly carrying case: Made from plant-based materials that absorb carbon dioxide, which causes global warming, and uses a fabric case that does not release harmful substances when discarded. ● Key: C ● Baroque system ● Double holes 3-piece construction ● C/C# double key ● Arched windway ● Includes thumb rest, cleaning rod, recorder cream, fingering chart, and case
