Aulos 521 bass recorder, black and beige design. - Model Name: Aulos 521 - Type: Bass Recorder - Accessories: Case, recorder reed, cleaning rod, grease - Colors: Black, Beige - Brand: Aulos Thank you for viewing. This was used by the daughter of a senior ensemble member until last year, but she graduated from the university and also from the ensemble, so I received it for 20,000 yen. It was used carefully, but there are some minor scratches. No claims and no returns are accepted. I am a novice at storage, and I have only tested the sound. Thank you very much.
