This is a resin oboe (so-called plastic oboe). I bought it used for beginner practice and played it for about a year. The lowest note is LOW B. All keys are in working condition and produce clear sound from LOW B to High D. I adjusted and attached the cork myself, but I don't think it significantly affects the playing feel. It has been about a year since I purchased it, and it has not undergone professional maintenance, so it might be best to have it adjusted once. The only accessory besides the main body is an aftermarket (GATOR) semi-hard case. This also shows signs of use within an acceptable range. Personally, I'm glad I started practicing with this oboe. It's very easy to play, and as you improve, you can produce a round, soft sound that you wouldn't expect from a plastic oboe. Also, due to the nature of the material, it is quite resistant to Japan's humidity and heat, making it easy to handle and allowing me to take it anywhere. It was a great joy to be able to play among the small trees in a large park. I got a new wooden oboe at the end of last year, so I don't have much time to play this plastic one anymore. I would be very happy if it could reach someone who will play it. It has been tested and is in working order, but as it is an older item, please be aware if you are looking for perfection. Thank you for your consideration.
