This is a Yamaha oboe. I purchased it used from JDR and used it for several years. The sticker from JDR at the time of purchase is attached in the 7th photo. When I bought it used, it was fully maintained, and the pads are clean. There is a repaired crack in the trill key area in the 4th photo, but it has been beautifully repaired. There are no other major scratches, and I think it is in relatively good condition. It is a JDR original model, which is a standard YOB431 model with upgraded key equipment. Retail price: Approximately 700,000 yen ⭐︎The outside of the case that came with it when I bought it used is sticky. This is probably due to deterioration, and there is also peeling on the surface (photo 5). If you are concerned, you may want to replace it. ・The case cover can be used without any problems, and it is in good condition except for some dullness on the metal fittings. ・It was adjusted at the beginning of December 2025 and is ready to use. ・Please feel free to ask any questions.
